Michelle Williams celebrated her Broadway debut last night at Studio 54, where she is currently putting her mark on the role of Sally Bowles in Roundabout Theatre Company's revival of Cabaret. The theatergoing community largely knows her from past film and television roles in projects like My Week With Marilyn, Brokeback Mountain, and, if we're going way back, the pinnacle of teen dramas, Dawson's Creek. However, TheaterMania was surprised to discover this hidden gem of Williams' early career — a guest spot on the scantily clad '90s series Baywatch as Bridget Bowers, a preteen cutie who catches the eye of David Hasselhoff's TV son. You almost won't believe she's the same girl strutting through the Kit Kat Klub.
