Most famous role: Jody Banks in The Fall Guy (1981-1986)

It would be easy to assume that Heather Thomas, the stuntwoman sidekick to Lee Majors in The Fall Guy, was all beauty and no brains. But the buxom blonde—who graced many a teenager's wall in the 1980s—quit acting in 1998 in order to focus on behind-the-camera pursuits. She sold a screenplay to Touchstone Pictures and had her first novel, Trophies, published in 2008.
