Carrie Fisher

Carrie Fisher was only 19 when filming began on a little sci-fi project called Star Wars. You wouldn't think a billowy, ankles-to-elbows white gown could be sexy, but as director George Lucas told Fisher, “There's no underwear in space.” Fortunately for every male born after 1950, space does offer the metal bikini Fisher wore in Return of the Jedi. In fact, the “Slave Leia” costume remains such a fixture in geek fantasies that fellow all-time hotties like Jennifer Aniston have donned it. It’s Fisher, though, who wins a place in our hearts as the original princess we'd square off against Lord Vader to save.
