Oblivion-Morgan-Freeman-Tom-CruiseWords to alert lawyers (and maybe unnerve Tom Cruise): HBO is finishing up a tough documentary on the Church of Scientology. The Hollywood Reporter says that a “bombshell” film on Scientology and its hold on some Hollywood stars will air in 2015. HBO confirmed only that Oscar winner Alex Gibney (“Taxi to the Dark Side”) is doing the film and HBO plans to run it. The film is expected to feature new revelations about the controversial church and its famous followers, such as Cruise and John Travolta. If it’s finished in time, it will be submitted to the Sundance Film Festival in January. THR says the film is based on the book, “Going Clear: Scientology, Hollywood, and the Prison of Belief,” by Pulitzer Prize-winning journalist Lawrence Wright. More
