Brian Austin Green

While many of his Beverly Hills, 90210 cohorts were reduced to pop-culture punch lines, this boyish actor and his perfectly arched eyebrows managed to eke out a career after the demise of that popular prime-time teen soap. After getting his start with a three-year stint on Knots Landing, Green moved to Beverly Hills in 1990. During his 10-year tenure on the show, he appeared in a handful of TV-movies and dated a few of his comely costars (Tiffani Thiessen and Vanessa Marcil, who is the mother of his son). During the lean years, he made occasional guest spots and directed an independent film. Green's luck changed in 2005 with a tongue-in-cheek cameo as himself in the feature Domino and a gig as Freddie Prinze Jr.'s sex-obsessed sidekick on the sitcom Freddie, although the show only lasted one season.
