According to THR, Wyatt, who directed Rise of the Planet of the Apes for the studio, has left Gambit due to script issues, an expanded budget, and delays that have caused a conflict with another project he has. What's that project? No idea. He's got nothing confirmed to be coming up. Here's his statement...
“I was very much looking forward to working with my friend Channing and the team at Fox, but regrettably a push in the start date now conflicts with another project. I thank them for the opportunity, and I know that Gambit will make a terrific film.”
Maybe that's true, but then again maybe not. Those delays pushed the film's start date to next March, which isn't a lot of time before the pegged October 7th 2016 release date. Wyatt may not be keen on that kind of time crunch. Tatum is still on board and so is co-star Lea Seydoux, but let's not forget how hard it was for Fox to land a director in the first place. It may be they choose a lesser name, perhaps an up 'n coming filmmaker who can make the movie they want to make in an extremely short amount of time.
