Before "Star Wars," there was "Thx 1138." A strange, dystopic science fiction movie packed with big ideas up to its eyeballs, "Thx 1138" is now mostly known as the feature directorial debut of one George Walton Lucas Jr. (though it also came back in conversation when the best episode of "Andor" paid homage to it). The future Lucasfilm founder originally created this story of repressed emotions and stymied sexuality as a student film, but by the time it was reimagined as a feature, it had gained backing from Warner Bros.

Lucas' American Zoetrope co-founder Francis Ford Coppola also had faith in the movie, and served as one of its producers. "Thx 1138" starred Robert Duvall, then already known for his work on stage and television, not to mention in films like "To Kill A Mockingbird," "M*A*S*H," and "True Grit." Future "Halloween" actor Donald Pleasence co-starred, along with a then-unknown actress named Maggie McOmie.
