Sarah Michelle Gellar

Sarah Michelle Gellar became a star in the campy TV series Buffy the Vampire Slayer. Gellar played Buffy Summers, a high school student who also happened to be the "chosen one" destined to battle vampires and other supernatural nasties. The show's goofy appeal made it a hit, and it aired from 1997-2003. Gellar was already an industry veteran before Buffy began: she starter her acting career as a pre-schooler and by the time she was 18 she had won a daytime Emmy for her work in the soap opera All My Children. She cemented her reputation as a horror queen by appearing in two teen horror films, I Know What You Did Last Summer (1997, with Jennifer Love Hewitt) and Scream 2 (1997, with Neve Campbell). She married actor Freddie Prinze, Jr. in 2002. They starred together in the 2002 movie version of the TV cartoon Scooby Doo and its 2004 sequel, Scooby Doo 2: Monsters Unleashed. She had another horror hit with the scary 2004 movie The Grudge and its 2006 sequel The Grudge 2.

Extra credit: The series Buffy the Vampire Slayer was based on a 1992 feature film by the same name; Kristy Swanson played Buffy in that film, which also starred Donald Sutherland and Paul "Pee-wee Herman" Reubens.
