The supposed announcement of a director was scapped at SDCC, Fox didnt want to announce until filming starts in October. They didnt want to get burned again by announcing a director to early.
The release date will move to November 22, 2019.
Do you really think a director can be hired for a Hollywood blockbuster without the trades getting wind of it? If they haven't announced a director it's because they don't have one.
If they had found a director they'd be shouting it from the rooftops, not trying to keep it a secret until filming starts. Literally nobody does that.
t:
I hear is somebody who has worked with Tatum on another movie.
They say it going to be a big surprise.
Maybe:
Roland Emmerich
The Coen Brothers
The Wachowskis
Quentin Tarantino- the biggest surprise.
Gambit has lost 3 directors in 3 years, that's a very clear sign that there's a fundamental problem with the project and that it is nowhere near being ready to film.
Any director worth their salt is going to want ample time to rework and develop this, not jump on a troubled production that will only have 3 or 4 months of pre-production before filming starts. You would want to give the director about a year before filming starts, so that would be next summer (If they got a director
now), which brings us to the biggest problem...
The Disney-Fox buy out will be complete before the end of the year, and Marvel won't be using anything of this project in the MCU.
Fox isn't going to pump $155m into such an underdeveloped project at the last minute when 1) it probably wouldn't be good enough to make it's money back and, 2) it has no future going forward anyway.
TL;DR - No director and the company is being bought out soon, this film is dead in the water.
