-Photo by NBC- Really? Is this what they need right now? One of the producers on Farrah Fawcett's cancer documentary, Farrah's Story, is suing the actress, Ryan O'Neal, and good friend Alana Stewart -- claiming that all three physically threatened and "otherwise blocked him from any role in the documentary" -- a project which he says he worked on for the past two years. Craig Nevius says his production company, Sweetened By Risk, signed contracts in 2004 to produce Chasing Farrah, a reality show about Farrah's life, and in 2008, they decided to turn her home movies into another documentary project tentatively titled A Wing and a Prayer. According to the lawsuit, Craig says he was contacted in September 2008 by Ryan, who "demanded" Craig release control of the project.
