What Happened to the Happy Days Cast?

“Happy Days” Actually Arrived Before American Graffiti

“Happy Days” was thought by many people to be an offshoot of the George Lucas film American Graffiti. That movie featured Ron Howard in a similar role. American Graffiti debuted before “Happy Days” but they were both in the works at the same time. “Happy Days” was only revisited because of the success of the movie.
