Haim’s numerous collaborations with fellow teen idol Corey Feldman, including The Lost Boys, License to Drive and Dream a Little Dream earned the pair the nickname “The Two Coreys.” They starred in the television reality show The Two Coreys, which aired on A&E for two seasons in 2007 and 2008. On the show, Feldman settled into domestic life while Haim continued his struggles. While both hoped to appear in a Lost Boys sequel, only Feldman ultimately did.
Haim told The Sun in 2004 that at one point he took 85 Valium a day.
“I started on the downers which were a hell of a lot better than the uppers because I was a nervous wreck,” he told the paper. “But one led to two, two led to four, four led to eight, until at the end it was about 85 a day. … The doctors could not believe I was taking that much. And that was just the Valium. I’m not talking about the other pills I went through.”
The Canadian-born Haim made his first feature film appearance was in 1984 in Firstborn, but his major break came in 1986 with his starring role in Lucas alongside Kerri Green, Charlie Sheen, and Winona Ryder. Following the film’s success, Haim starred in the 1987 television series Roomies.
