Don't kid yourself. Hollywood fully supports the Sundance film festival and the film being there. All of their celebrities support it being there. Robert Redford supports the movie being there otherwise it wouldn't be there. They would embrace it if they didn't think there was going to be some sort of backlash against them. All in the name of "getting the word out there" on child rape - which is completely bogus.
I'm talking about financial support. The whole point of Sundance is to shop around these fringe films that couldn't find mainstream financing amongst Hollywood studios. When Harvey Weinstein doesn't want your movie...you're fringe! 90% of what plays at Sundance is close to worthless from a cinematic point of view. My point is that instead of blaming some non-existent Hollywood monolith talk about the person who actually made this film (writer, director, producer Deborah Kampmeier).
Michael Jackson, Peter Yarrow, and Roman Polanski are not complete outcasts in the entertainment industry.
