Most famous role: Sloane Peterson in Ferris Bueller's Day Off (1986)

In 1986, every guy wanted to be Ferris Bueller...and wanted Sloane Peterson as his girlfriend. It's understandable. Whereas many teen movies (even today) prefer to equate "girlfriend" with "drag," Mia Sara proved she could hang with the guys. And did it again in 1994, when she starred opposite Jean-Claude Van Damme in Timecop.
