In "A New Hope", 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.
