Which 1977 film was directed by George Lucas?

Mr. Lucas should direct Dr. Doom, I believe he'll do a better job than The MCU!! Since it's Dr. Doom who inspired his Darth Vader

"they considered it fair, and he considered it fair, to pay them for the full hour. That was the way they did business...."

This movie changed my life. It's so rooted in mythology and the language of cinema; right in my sweet spot. Seen it well over 100 times.
