Michael Douglas
Cheerleading was actually a primarily male sport up until the 1950s. Choate Preparatory School was where, as with the rest of them, Douglas learned to cheer, chant, tumble, and stunt. As scientist Hank Pym, he followed another former male cheerleader (Paul Rudd) when he was cast in the Marvel movies.
Megan Fox
Before she broke hearts in Transformers, Megan attended Morningside Academy in Port St. Lucie, Florida. At her school, the bombshell was mocked, turning to athletics for security. She began acting in movies like Teenage Drama Queen Confessions, where she played a cheerleader!
