The actor has talked about the abuse he suffered but has never named any of the people, believed to be prominent Hollywood types, until now.
Feldman told Williams that the documentary will name who abused them and that, "The one main name that everyone is waiting to hear. It is a name that everybody on the planet knows."
Feldman's revelation that his life had been threatened because of the documentary left the host speechless, with Williams saying, "I'm frightened for you. You've only got you and [your wife] against the world."
After trying to sell the documentary to streaming services who all declined, Feldman funded it himself and will now premiere it on its own website on Monday.
