As a 16-year-old, Martin Starr made an indelible impression on television viewers as the sweet, awkward Bill Haverchuck on Freaks & Geeks. Ten years later, he's blossomed into a successful adult actor. He was featured in Knocked Up and Good Dick, among other films, and currently has prominent parts in the Starz series Party Down and the wonderful new film Adventureland. Both roles call on his unique sense of humor, surprising shades of darkness, and his almost palpable sense of decency. We talk with Martin about how he's grown from a teenager overwhelmed by Hollywood to an adult with his own voice.
