Madsen portrayed Helen Lyle, a graduate student working on a thesis about urban legends who pursued Candyman and faced horrifying consequences as a result. A star since she was a teenager, Madsen rose to fame with films like Dune and Zombie High. Post-Candyman, she starred in The Rainmaker and Star Trek: Voyager and was the long-running host of Unsolved Mysteries. But her biggest moment came in 2004 when she was nominated for an Oscar for her leading role in Sideways. Madsen currently stars in AMC's Hell on Wheels.
