Michelle Williams
The Halloween franchise brought attention to a number of future A-list stars, and that includes Michelle Williams. Williams plays Molly Cartwell, the girlfriend of Laurie Strode's son. Fortunately, Williams' character is one of the few who make it out of the film in one piece.
Joseph Gordon-Levitt
While technically Halloween H20: 20 Years Later wasn't his first role, Joseph Gordon-Levitt's performance earned him enough attention to jumpstart a lucrative acting career. Gordon-Levitt plays Jimmy Howell, Laurie Strode's teenage neighbor and an unfortunate victim of Michael Myers. It wasn't long before Gordon-Levitt was moving on to bigger roles in films like 10 Things I Hate About You (1999) and Mysterious Skin (2004).
