9. Kristin Bell, The Adventures of Tom Sawyer
Veronica Mars, Broadway star? Well, not exactly, but pretty close: Kristen Bell was in her senior year at NYU when she was cast as Becky Thatcher in the Broadway musical version of The Adventures of Tom Sawyer. Unfortunately the show tanked—it closed after only about two weeks of performances—but Kristen landed Veronica Mars a few years later, and the rest, as they say, is history. Veronica Mars even made use of her vocal talents in a memorable karaoke scene in the second season, so at least there’s that! This particular video was taped as part of the Rosie O’Donnell Show on April 19, 2001.
