10 Best One-Hit-Wonder Actors

Though her film career began with 1993's The Crush, it wasn't until 1995's Clueless hit theaters that Alicia Silverstone became a star. The ever-growing popularity of that film is a testament to how well Silverstone made the character of Cher Horowitz her own, and it helped launch a successful career.

Silverstone went on to star in a ton of movies and television series, but despite showing up as one of the heroes in Batman & Robin alongside a ton of appearances all over TV, Silverstone's career has been anchored to Clueless.

This is partly due to the fact that it was her breakout performance, but it's mostly due to the cult status of Clueless. That movie introduced the world to a new, contrived way of talking, and it somehow caught on. Eventually, a spin-off sitcom hit the airwaves, and an entire book series was published about Clueless, which is in line for a potential remake.

These days, Silverstone remains an active actor, but her time is mostly taken up through her roles as an activist. She's worked as an animal rights and environmental activist for years, and she was voted Sexiest Female Vegetarian by PETA in 2004.
