George Lucas's science fiction multi-film "Star Wars" saga has had a significant impact on modern popular culture. "Star Wars" references are deeply embedded in popular culture; references to the main characters and themes of "Star Wars" are casually made in many English-speaking countries with the assumption that others will understand the reference. Darth Vader has become an iconic villain, while characters such as Luke Skywalker, Han Solo, Princess Leia, C-3PO, R2-D2, and Chewbacca have all become widely recognized characters around the world. Phrases such as "evil empire", "May the Force be with you", Jedi mind trick, and "I am your father" have become part of the popular lexicon. The first "Star Wars" film in 1977 was a cultural unifier, enjoyed by a wide spectrum of people.
