delivering on the vision of a world-renowned filmmaker

George Lucas had a vision: he wanted movie lovers everywhere to experience his movies —exactly the way he envisioned, and exactly as they were created in the studio. Unfortunately, cinemas didn’t have the existing technology setup to do so. Lucas and team designed a certification program to counter these challenges.

THX was born—and made available to moviegoers with the release of Star Wars Episode VI: Return of the Jedi. Now, over thirty-five years later, products bearing the THX brand still ensure you’re getting the truest sense of the artist’s vision—audio and video—in the cinema, at home, and on the go.
