Just a few weeks after making a surprise appearance on the Hall H stage at Comic-Con while wearing a Gambit t-shirt, Channing Tatum is reportedly planning to leave the project. The Wrap reports that the actor's deal with 20th Century Fox is "in jeopardy of falling apart," while insiders claim that director Rupert Wyatt may have to start looking for a new leading man. One source said that negotiations are still ongoing between the actor and 20th Century Fox, but the source did admit that "something is up."

The shake-up comes just as the studio is in the process of testing female leads alongside Channing Tatum, including Spectre star Léa Seydoux. Channing Tatum was also set to produce Gambit with his partner Reid Carolin, but it isn't known if he plans to stay on as a producer, or if producers Lauren Shuler Donner and Simon Kinberg will continue on without them. Whatever the case may be, a decision will have to be made very soon.

Just a few days ago, a report surfaced that the superhero movie will start production this fall, in Channing Tatum's hometown of New Orleans, with casting already under way for a number of supporting characters. Joshua Zetumer wrote the screenplay, but no story details have been given at this time. It isn't immediately known what is causing the deal between Channing Tatum and the studio to collapse, but if he does in fact leave the project, it would be quite surprising, since the actor heavily campaigned for the role through social media and various interviews, while he was promoting 22 Jump Street last year.

In a recent interview with Grantland, the actor's producing partner Reid Carolin revealed that he and the actor plan on making their directorial debut soon, but no details about that unspecified project were revealed. He is also attached to star in Sony's 23 Jump Street, although it isn't known how far along in development that sequel is at this time. He has also been rumored to star in Ghostbusters 4 for Sony Pictures, but that has never been confirmed.

Channing Tatum's reps and 20th Century Fox have not commented on the report, so we'll have to wait and see if the actor actually parts ways with Gambit. If he does back out, who do you think should step in and play Remy LeBeau in this long-awaited superhero movie? Chime in with your thoughts, and stay tuned for the latest updates on Gambit.
