American Anthem
When an Olympic gold medal-winning gymnast plays the role of a gymnast in the film, you’d figure that it would vastly improve the movie. Unfortunately, that didn’t happen at all in American Anthem, when gold medalist Mitchell Gaylord played Steve Tevere, an ex-football star who gives up gymnastics to work as a motorcycle mechanic. The film turned out to be a disaster, scoring a 0% on Rotten Tomatoes, and Gaylord earning a Razzie for his performance. At least in 2007, he was named the seventh-best US gymnast of all time.
