There's trouble brewing on the set of Disney's "Maleficent," the Angelina Jolie-starring live action movie delving into the back story of the villain at the heart of "Sleeping Beauty." The Hollywood Reporter writes that the movie will undergo reshoots to fix problems with its opening, with several new scenes written by director John Lee Hancock."Maleficent" producer Joe Roth tells THR that Hancock will be brought on in a supervisory role, but that he would not be taking over directing duties from Robert Stromberg, who's making his feature directorial debut."We asked him to be on set," Roth said of Hancock. "He's not directing. He wrote pages and I hired a first-time director and it's good to have him on set."Stromberg won production design Oscars for his work on "Alice in Wonderland" and "Avatar," and Roth noted that it was Stromberg's reputation for such attention to beautiful detail that secured him the job. Hancock would merely be helping iron out the opening, Roth said, which anonymous sources told THR was completely rewritten by Hancock."The movie is gorgeous to look at and the last 75 minutes are really entertaining," Roth said.The reshoots, to take place over eight days, will not involve Jolie. "Maleficent," which has a budget in excess of $200 million, is still expected to keep its planned opening date of May 30, 2014.
