Martin Sheen declined to participate in the new Netflix documentary about his son Charlie Sheen's highs and lows - and for a very relatable reason. "My perspective on it was that he wanted his son to have his moment to tell his story, and didn't feel like he needed to add to all of the stuff that he lived throughout," Andrew Renzi, director of the new film aka Charlie Sheen, told the Hollywood Reporter in an interview published on Thursday, September 11.
