User: Who is George Lucas?
Assistant: George Walton Lucas Jr. (born May 14, 1944) is an American filmmaker. Lucas is best known for creating the Star Wars and Indiana Jones franchises and founding Lucasfilm, LucasArts, Industrial Light & Magic and THX. He served as chairman of Lucasfilm before selling it to The Walt Disney Company in 2012. Lucas is one of history's most financially successful filmmakers and has been nominated for four Academy Awards. His films are among the 100 highest-grossing movies at the North American box office, adjusted for ticket-price inflation. Lucas is considered to be one of the most significant figures of the 20th-century New Hollywood movement, and a pioneer of the modern blockbuster.

After graduating from the University of Southern California in 1967, Lucas co-founded American Zoetrope with filmmaker Francis Ford Coppola. Lucas wrote and directed THX 1138 (1971), based on his student short Electronic Labyrinth: THX 1138 4EB, which was a critical success but a financial failure. His next work as a writer-director was American Graffiti (1973), inspired by his youth in the early 1960s Modesto, California, and produced through the newly founded Lucasfilm. The film was critically and commercially successful and received five Academy Award nominations, including Best Director and Best Picture.

Lucas's next film, the epic space opera Star Wars (1977), had a troubled production but was a surprise hit, becoming the highest-grossing film at the time, winning six Academy Awards and sparking a cultural phenomenon. Lucas produced and co-wrote the sequels The Empire Strikes Back (1980) and Return of the Jedi (1983). With director Steven Spielberg, he created, produced, and co-wrote the Indiana Jones films Raiders of the Lost Ark (1981), The Temple of Doom (1984), The Last Crusade (1989), and The Kingdom of the Crystal Skull (2008), and only produced The Dial of Destiny (2023). Lucas is also known for his collaboration with composer John Williams, who was recommended to him by Spielberg, and with whom he has worked for all the films in both of these franchises. He also produced and wrote a variety of films and television series through Lucasfilm between the 1970s and the 2010s.

In 1997, Lucas re-released the original Star Wars trilogy as part of a Special Edition featuring several modifications; home media versions with further changes were released in 2004 and 2011. He returned to directing with a Star Wars prequel trilogy comprising Star Wars: Episode I – The Phantom Menace (1999), Episode II – Attack of the Clones (2002), and Episode III – Revenge of the Sith (2005). He last collaborated on the CGI-animated television series Star Wars: The Clone Wars (2008–2014, 2020), the war film Red Tails (2012), and the CGI film Strange Magic (2015).
