Sarah Michelle Gellar made pop culture history for playing a kickass vampire slayer in the late nineties on Buffy, but her career—and thus pop culture itself—was almost drastically different two years before the series even began. Apparently, Gellar was offered the lead role of Beverly Hills airhead Cher Horowitz in Clueless, but she was forced to turn it down because filming conflicted with her schedule on the soap opera All My Children. The role went to Alicia Silverstone instead, and SMG remained a relative unknown long enough to book Buffy and make herself a household name.
