Corey Feldman has no idea what it's like not to be famous. After all, he starred in a McDonald's ad when he was just 3 years old. But being famous and underage, he said, caused serious damage to him and his friends, including loss of innocence and a lost childhood. Feldman blamed the adults around him, not just those looking to profit from charming children, but also some with far more sinister motives. I can tell you that the No. 1 problem in Hollywood was and is and always will be pedophilia. That's the biggest problem for children in this industry. ... It's the big secret," Feldman said. The "casting couch," which is the old Hollywood reference to actors being expected to offer sex for roles, applied to children, Feldman said. "I was surrounded by [pedophiles] when I was 14 years old. Didn't even know it. It wasn't until I was old enough to realize what they were and what they wanted till I went, Oh, my God. They were everywhere," Feldman, 40, said. The trauma of pedophilia contributed to the 2010 death of his closest friend and "The Lost Boys" co-star, Corey Haim, Feldman said. "There's one person to blame in the death of Corey Haim. And that person happens to be a Hollywood mogul," Feldman said, adding that he, too, had been sexually abused by men in show business. Feldman said his realization followed the discovery of what some adults around him had allegedly done to other children. "There was a circle of older men around this group of kids. And they all had either their own power or connections to great power in the entertainment industry," he said.
