George Lucas' 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, Princess Leia, Han Solo, Chewbacca, R2-D2, and C-3PO have all become widely recognised characters around the world. Phrases like "evil empire", "May the Force be with you", and most famously "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.
Many efforts produced in the science fiction genre (particularly in film) can now be seen to draw heavy influence and inspiration from the original Star Wars trilogy as well as the magnitude of sequels, spin-offs, series, games and texts that it spawned. Sounds, visuals, and even the iconic score of the films have become integral components in the tapestry of American society. The film can be said to have helped launch the science fiction boom of the late 1970s and early 1980s, making science fiction films a blockbuster genre. This very impact also made it a prime target for parody works and homages, with popular examples including Spaceballs, Family Guy's "Blue Harvest" special, Seth Green's "Robot Chicken: Star Wars", and Lucas' self-proclaimed favorite parody, "Hardware Wars" by Ernie Fosselius.
