Which space opera franchise did George Lucas create? George Lucas created the Star Wars franchise.

The franchise began with the film Star Wars, released in 1977. Lucas wrote and directed the original movie, drawing inspiration from space-adventure serials, mythology, westerns, and the work of filmmakers such as Akira Kurosawa. Its success transformed a risky science-fiction project into a global entertainment phenomenon.

Star Wars expanded beyond the original trilogy into prequel and sequel films, animated series, live-action television, novels, comics, video games, toys, theme-park attractions, and other media. Lucas founded Lucasfilm to produce and control the project, along with related filmmaking and effects work.

The alternatives are neighboring science-fiction franchises but have different creators: Dune originated with Frank Herbert’s novels, Battlestar Galactica was created by Glen A. Larson, and Star Trek was created by Gene Roddenberry. Lucas also created the Indiana Jones franchise’s story concept with Steven Spielberg, but it is not a space opera.
