1. Sarah Michelle Gellar (Buffy Summers)
Since her vamp-stabbing days, Gellar has gone on to star in horror films like The Grudge, The Grudge 2, and Possession. In 2002, she got hitched to '90s heartthrob Freddie Prinze Jr. (let's try to forget about their co-starring role in that terrible Scooby Doo movie) before signing on to CBS' The Crazy Ones (co-starring the late Robin Williams). It was unfortunately canceled in the spring of 2014. We guess there's a reason she really misses being Buffy.
