Bryan Singer came back to the X-Men franchise he started and pretty much hit it out of the park with X-Men: Days of Future Past, a film that was waaaay better than it had any right to be. Could he pull that trick off with X-Men: Apocalypse, a movie that promises to focus on a lamer, later-period X villain and the kind of destruction audiences have begun to tire of seeing? According to Radar Online we may never know.
The gossip site - with a spotty track record, it's fair to note - is reporting that the studio is trying to push Singer off the project because of his recent legal troubles, ie being sued over alleged sex abuse. According to the site Singer has shown the studio his defense, which apparently clears up the whole issue, but the bean counters remain fearful. It's not that they think Singer did it so much as they're worried about the publicity and also how any potential court proceedings could impact their film, which is scheduled for just two years from now. Basically Singer has to jump right into making that movie, and if there is a courtroom showdown it might delay things.
This sounds like the sort of studio second-guessing you would expect. In the end this has nothing to do with Singer's guilt or innocence (and lots of evidence point to him being innocent of these charges) but rather the problems that arise from the entire scandal. That said, the main reason why I question this story is that Singer has, after a few months away, returned to Twitter - tweeting as recently as one hour ago. This seems like the behavior of a very confident guy.
Of course if Days of Future Past keeps making good money this is all moot. It will probably wind up as the second best-earning X film domestically, and it is already far and away the most successful film internationally. Money smoothes over lots of wrinkles in Hollywood.
