Hopefully you weren’t that excited for ‘World War Z’. Paramount has brought on ‘Prometheus’ screenwriter Damon Lindelof to retool the Brad Pitt-led adaptation of Max Brooks’ famed zombie novel-with specific focus being placed on the film’s third act. That would par for the Hollywood-blockbuster course, except for one small detail: ‘World War Z’ finished filming last year. THR.com broke the news of Lindelof’s hire, while noting that ‘World War Z’ will undergo “significant re-shoots” likely starting this fall. For Paramount, this is the second high-profile film to require major post-production changes. Last month, ‘GI Joe: Retaliation’ was moved from its June 29 release date to March 29, 2013. The studio line was that ‘GI Joe’ was being retrofitted into 3D to help with overseas revenues, but Deadline.com reported that test audiences were unhappy with Channing Tatum’s brief role in the film. His part could be expanded with additional re-shoots, but Tatum hadn’t heard about any last week at the MTV Movie Awards. “I don’t know. Truly,” Tatum said. “I did my part and then all this stuff is going on, so they haven’t come to talk to me about anything.” As for ‘World War Z’, the film was initially scheduled to hit theatres on December 21, but was moved to next June earlier this year. That would give director Marc Forster plenty of time to work in the new ending that Lindelof writes, but whether the director gets the chance is certainly up for debate.
