R2-D2
R2-D2 () or Artoo-Detoo is a fictional robot character in the Star Wars franchise created by George Lucas. He has appeared in ten of the eleven theatrical Star Wars films to date. At various points throughout the course of the films, R2, an astromech droid, is a friend to C-3PO, Padmé Amidala, Anakin Skywalker, Leia Organa, Luke Skywalker, and Obi-Wan Kenobi. R2-D2 and his companion C-3PO are the only characters to appear in every theatrical Star Wars film, with the exception of Solo: A Star Wars Story (2018).
English actor Kenny Baker played R2-D2 in all three original Star Wars films and received billing credit for the character in the prequel trilogy, where Baker's role was reduced as R2-D2 was portrayed mainly by radio controlled props and CGI models. In the sequel trilogy, Baker was credited as consultant for The Force Awakens; however, Jimmy Vee also co-performed the character in some scenes. Vee later took over the role beginning in The Last Jedi. In The Rise of Skywalker, puppeteers Hassan Taj and Lee Towersey perform the role of R2-D2, replacing Jimmy Vee, who had played the role in the previous two films. His sounds and vocal effects were created by sound designer Ben Burtt.
R2-D2 was designed in artwork by Ralph McQuarrie, co-developed by John Stears and built by Peteric Engineering. The revised Empire Strikes Back droids had fibreglass shells built by Tony Dyson and his White Horse Toy Company.

Design
George Lucas's creation of R2-D2 was influenced by the peasant Matashichi from Akira Kurosawa's 1958 feature film The Hidden Fortress (released in the United States in 1962), although his personality is completely the opposite. Lucas and artist Ralph McQuarrie also drew inspiration from the robots Huey, Dewey, and Louie from Douglas Trumbull's 1972 film Silent Running.
Around the same time that A New Hope was being shot, Ray Harryhausen had already created "Bubo" for the 1981 film Clash of the Titans. In the film, Bubo is a mechanical metal owl that flies heavily and communicates through whistles and tweets. Harryhausen denied a relation.The name derives from when Lucas was making one of his earlier films, American Graffiti. Sound editor Walter Murch states that he is responsible for the utterance which sparked the name for the droid. Murch asked for Reel 2, Dialog Track 2, in the abbreviated form "R-2-D-2". Lucas, who was in the room and had dozed off while working on the script for Star Wars, momentarily woke when he heard the request and, after asking for clarification, stated that it was a "great name" before going back to writing his script.R2-D2 stands for Second Generation Robotic Droid Series-2, according to a Star Wars encyclopedia published after the release of the film Star Wars. Tony Dyson, owner of the special effects studio The White Horse Toy Company, was commissioned by special effects supervisor Brian Johnson to fabricate the revised mechanical design for The Empire Strikes Back, making several units operated by remote control. A number were used by Baker, and two were stunt double models made for the scene where the droid was shot from the swamp onto the shore on Dagobah.

Appearances
Skywalker saga
Original trilogy
Star Wars
In Star Wars, R2-D2 and C-3PO (Anthony Daniels) are both introduced on board the Tantive IV, along with Princess Leia (Carrie Fisher) of Alderaan, when they are being pursued upon by Darth Vader (portrayed by David Prowse, voiced by James Earl Jones) aboard an Imperial Star Destroyer. Leia inserts into R2-D2 an information disc containing the plans for the Death Star battle station, and encodes a distress message on the droid's holographic projector. The droids then escape in a pod that crashes on Tatooine near Jedi Master Obi-Wan Kenobi's (Alec Guinness) desert abode.
R2-D2 and C-3PO are then abducted by Jawas and bought by Owen (Phil Brown) and Beru Lars (Shelagh Fraser), uncle and aunt of Luke Skywalker (Mark Hamill). While Luke cleans the sand out of R2-D2's gears, he discovers a fragment of Leia's message, and removes the droid's restraining bolt to see more; once free of the bolt, R2 claims to have no knowledge of the message. That night, R2-D2 leaves the farm to seek out Obi-Wan. When Owen and Beru are killed by Imperial stormtroopers, Luke is forced to leave Tatooine with Obi-Wan, Han Solo (Harrison Ford), and Chewbacca (Peter Mayhew) on board the Millennium Falcon to deliver R2-D2 to the Rebel Alliance. On their arrival at Alderaan's co-ordinates, they are pulled in by the Death Star's tractor beam and are forced to land, but eventually rescue Princess Leia. After Vader kills Obi-Wan, the rest of the group escapes and delivers the Death Star plans to the Rebel Alliance. R2 later serves as Luke's droid during the attack on the station. R2-D2 is severely damaged during the battle, but is repaired before the ceremony at the end of the film.

The Empire Strikes Back
In The Empire Strikes Back, R2-D2 accompanies Luke to Dagobah, and later to Cloud City, where he helps to rescue and repair a heavily damaged C-3PO and to override city security computers. He also manages to reactivate the Millennium Falcon's hyperdrive, resulting in a last-minute escape from Imperial forces.

Return of the Jedi
In Return of the Jedi, R2-D2 plays a critical role in rescuing Luke, Leia, and Han from Jabba the Hutt. He later joins the Rebel strike team on Endor. He is badly damaged during the battle between the Imperial troops and the Rebels, but is repaired in time for the celebration marking the second Death Star's destruction and the fall of the Empire.

Prequel trilogy
The Phantom Menace
In The Phantom Menace, set 32 years before A New Hope, R2-D2 is portrayed as belonging to the Naboo defense forces, one of three astromech droids deployed for repair duty onboard Queen Padmé Amidala's (Natalie Portman) starship as it attempts to get past the Trade Federation blockade. The sole survivor of the three, R2-D2 repairs the deflector shields and saves the day. Having proved his worth, R2-D2 then becomes part of Jedi Master Qui-Gon Jinn's (Liam Neeson) party on Tatooine where he meets C-3PO and Anakin Skywalker (Jake Lloyd). Later still, he serves as the astromech droid for Anakin's starfighter during the Battle of Naboo.

Attack of the Clones
In Attack of the Clones, set 10 years after The Phantom Menace, R2-D2 again serves Anakin (Hayden Christensen) and Obi-Wan (Ewan McGregor). He accompanies Anakin and Padmé to Naboo, and then to Tatooine when Anakin tries to rescue his mother Shmi (Pernilla August). Here, he is reunited with C-3PO, and the two get into various misadventures on Geonosis. He and C-3PO are later witness to Anakin and Padmé's secret wedding.

Revenge of the Sith
In Revenge of the Sith, R2-D2 helps Anakin and Obi-Wan in their mission to rescue Chancellor Palpatine (Ian McDiarmid) from Count Dooku's (Christopher Lee) capital ship, the Invisible Hand. He is attacked by super battle droids, but defeats them through ingenious tactics. After Anakin falls to the dark side of the Force and becomes Darth Vader, he takes R2-D2 with him when he goes to assassinate the Separatist council, but tells him to stay with the ship. After the Galactic Empire is established at the end of the film, C-3PO's memory is erased to keep the knowledge of the locations of Vader and Padmé’s newborn children, Luke and Leia, a secret from their father. However, R2-D2's memory is not wiped; as a result, R2-D2 is the only surviving character at the end of the saga who knows the entire story of the Skywalker family. Both R2-D2 and C-3PO end up in the possession of Captain Raymus Antilles (Rohan Nichol) onboard the Tantive IV.

Sequel trilogy
The Force Awakens
In Star Wars: The Force Awakens, set approximately 30 years after Return of the Jedi, R2-D2 is revealed to be kept in storage at the Resistance base on the planet D'Qar, having put himself in a low-power mode after Luke Skywalker's disappearance. He later awakens and reveals Luke's location by combining map data stored in his memory with that of the droid BB-8. He then travels with Rey (Daisy Ridley) and Chewbacca to the planet highlighted on the map, where they find Luke in self-imposed exile. In the credits, Kenny Baker was credited as 'R2-D2 consultant,' while Jimmy Vee provided an uncredited portrayal in some scenes.

The Last Jedi
R2-D2 appeared in Star Wars: The Last Jedi, with actor Jimmy Vee taking over the role from Kenny Baker, who retired from the role due to his age and health.

He is later shown interfacing with the Falcon's computer while Rey and Chewbacca pilot the ship amid the final confrontation with the evil First Order’s forces.

The Rise of Skywalker
R2-D2 returns once more in Star Wars: The Rise of Skywalker. Initially remaining at the Resistance base, he is shown watching Leia as she dies. He later plays an important role in restoring C-3PO's memory after Rey, Finn (John Boyega) and Poe Dameron (Oscar Isaac) are forced to erase it so the droid can translate a Sith artifact that holds a clue to the location of the Sith homeworld and the new fleet of the resurrected Palpatine. R2-D2 accompanies Poe in his X-wing for the final assault, and is later shown joining the others in celebrating the defeat of Palpatine and the Sith Eternal.

Production
Several R2-D2 models were built for the original Star Wars films; one that was remote controlled and rolled on three wheeled legs, and others which were worn by English actor Kenny Baker and walked on two legs. Deep Roy (who also doubled Yoda in several scenes), served as Baker's double, in both Episodes V and VI; providing stunts and filling in when Baker was unavailable. The original props for Star Wars Episode IV: A New Hope were designed by John Stears and built by Stears' team and Peteric Engineering. The revised fibreglass droids used in The Empire Strikes Back were built by Tony Dyson and the White Horse Toy Company. The radio controlled R2 was operated by John Stears in A New Hope, Brian Johnson in The Empire Strikes Back and by Kit West in Return of the Jedi.
Kenny Baker, who portrayed R2-D2 in costume, was not involved in the Star Wars Holiday Special. R2-D2 was portrayed entirely by a radio controlled unit, operated by Mick Garris (Lucas' receptionist at the time). In the credits, R2-D2 is credited as playing himself. Garris later went on to operate the radio controlled R2-D2 at various events, including the Oscars.There were a total of 15 R2-D2s on the set of Attack of the Clones. Eight were radio-controlled; two were worn by Baker; the remainder were stunt models that could be moved by puppet strings or towed by wires. The robotic R2-D2's were prone to failure, particularly while shooting the Tatooine scenes in Tunisia.Radio-controlled units were extensively utilized for the Prequel trilogy due to advances in technology, though Baker was still used in some scenes. R2-D2 had three principal operators: Don Bies, Jolyon Bambridge and Grant Imahara.The sound effects for R2-D2's "voice" were created by sound designer Ben Burtt, using an ARP 2600 analog synthesizer, as well as his own vocalizations processed through other effects. Original props of R2-D2 and C-3PO are used as Audio-Animatronics in the queue area of Disneyland's Star Tours–The Adventures Continue attraction.
Although Kenny Baker is credited, Anthony Daniels (who portrays C-3PO) has stated that Baker did not film any scenes in Revenge of the Sith. Baker himself has said he probably only appears in footage caught while shooting the previous two movies.For The Force Awakens, producer Kathleen Kennedy hired two fans, Lee Towersey and Oliver Steeples, to build new R2-D2 robots for the film, after being impressed by their working replicas that were brought to Star Wars Celebration Europe in 2013.
Towersey was also one of the two puppeteers, along with Hassan Taj, who operated the droid in The Rise of Skywalker.

Cultural influence
R2-D2 was inducted into the Robot Hall of Fame in 2003 in Pittsburgh, Pennsylvania. A replica can be seen at the Carnegie Science Center in Pittsburgh. The Smithsonian Institution included R2-D2 in its list of 101 Objects that Made America. In 2022 R2-D2 was surveyed as being the most popular movie robot in the United States.The Phalanx CIWS is nicknamed R2-D2 due to the shape of the radar housing.Marc Rotenberg of the Electronic Privacy Information Center called a security robot intended for schools and malls R2-D2's "evil twin"; William Santana Li, who co-founded the company that built the robot, said he wanted people to think of the robot as "a mash-up of Batman, Minority Report and R2-D2".R2-D2 and C-3PO guest starred in a two episodes of Sesame Street in 1980. The two droids were featured as presenters at the 50th Academy Awards.
In the Pinky and the Brain final series "Star Warners" who parodies Star Wars Brain plays R2-D2 and Pinky plays C-3PO.
Ewan McGregor, who portrayed Obi-Wan Kenobi in the Star Wars prequel trilogy, said in an interview, "As soon as R2-D2 comes on the set, everyone goes a bit silly." He said "there is something about him that makes you feel great affection for him". In the DVD audio commentary for Revenge of the Sith, George Lucas says R2-D2 is his favorite character, and that it is intentional that R2-D2 saves the day at least once in every film.
R2-D2 had appeared in some episodes of The Simpsons. Also in the sixteenth Halloween special ("Treehouse of Horror XVI") in the I've Grown a Costume on Your Face segment Apu Nahasapeemapetilon appears disguised and later turned into a real version of R2-D2.
R2-D2 is parodied in several episodes of Family Guy. The final scene in "Blind Ambition" where Peter Griffin receives a medal of honor after a blind Peter saves Horace's life parodies the ending in the original 1977 Star Wars. In the episodes parodying the original Star Wars trilogy, Cleveland Brown plays R2-D2's role, while Quagmire plays C-3PO.
The 2015 Israeli sci-fi comedy OMG, I'm a Robot! features "Robo Joseph" – a "Jewish R2-D2" dubbed by Rob Schneider.In 2015, Hasbro released a Bop It game using the design of R2-D2 on September 4, 2015 for "Force Friday". The top part of the unit (his head) becomes the 'Bop It' button, the bottom part of his head becomes the 'Twist It' and his legs are the 'Pull It'. The game is based on the Bop It Micro Series and the voice is replaced with voice recordings from C-3PO. Instead of the game saying "I'm going to sleep." before the unit shuts off, this version says "I'll just switch off for a while."The navigation system of the SR-71 plane has been affectionately called R2-D2. The system had R2-D2 like navigational purposes and was mounted behind the pilot directed upward.
The telescope dome of Zweibrücken Observatory in Germany was repainted to resemble R2-D2 in 2018.
In the Latin American Spanish dubbing of the Star Wars films, the name R2-D2 is pronounced as "Arturito" (Little Arthur), which sounds similar to the English pronunciation.In the Italian version of the original trilogy, R2-D2 was named "C1-P8". Anglicisms were not common in the Italian language during the 1970s and 1980s, and the names of various characters were changed to be easier to pronounce and recognize for Italian speakers. Some of these changes were reverted in the dubbing of the prequel and sequel trilogies, where the original name R2-D2 was used instead. Other name changes in the Italian version of the original trilogy include C-3PO, Han Solo, Leia Organa and Darth Vader, who were called respectively "D-3BO", "Ian Solo", "Leila Organa" and "Dart Fener" (or "Lord Fener").
