Adam Shankman

Acclaimed movie producer and director Adam Shankman is best known for his upbeat, family-friendly movies, including "Hairspray," "A Walk to Remember" and "The Pacifier," but behind the scenes, Shankman says he spent years grappling with substance abuse and self-loathing. Growing up in Hollywood, Shankman, who is openly gay, remembers being "an incredibly happy kid." But when he was three years old, he says, his parents set him up with a doctor who was doing a study on sexual identity. Unbeknownst to his parents at the time, Shankman says he was placed in "conversion therapy." When he was a teen, Shankman turned to alcohol and later drugs to quiet the "ugly voice" in his head. In 2012, Shankman says, he entered a "really dark" place and the following year checked himself into a month-long rehab program -- where he discovered meditation.
