After a federal sexual abuse lawsuit was filed against filmmaker Bryan Singer in April, many wondered whether or not the allegations would affect the box office performance of his new mutant adventure X-Men: Days of Future Past. That obviously wasn't the case, since the superhero sequel has earned over $610 million worldwide after just three weeks of release, but the lawsuit has reportedly prompted 20th Century Fox to try and pull him off of the forthcoming sequel X-Men: Apocalypse.

Here's what an insider from Radar Online had to say, revealing that the studio believes the lawsuit against Bryan Singer may heavily impact the production.

"Fox isn't confident in it not heavily impacting production. Bryan's lawyers are going nuts because the deal was closed months ago."

We reported back in December that Bryan Singer was directing X-Men: Apocalypse, which was teased in the end credits sequence of X-Men: Days of Future Past, featuring a young Apocalypse building the pyramids in Egypt through telekinesis. The filmmaker reportedly provided 20th Century Fox with proof that the lawsuit was false, but the studio only cares about the bottom line, and there have been talks about who else Bryan Singer might allow to direct X-Men: Apocalypse, although those talks have not ended well.

"They don't really care whether he's innocent or guilty - they're only concerned with the bottom line, which is giving him another $250 to $350 million to make Apocalypse. There have been talks about who else he'd let direct it, with him producing, but those led to heated arguments and walk outs."

20th Century Fox is also considering pushing the production date, in case the lawsuit does go to trial, but if X-Men: Days of Future Past continues to do well at the box office, they may still let him direct X-Men: Apocalypse.

"If Days of Future Past does big, big business (not just opening weekend, but has 'legs'), it'll be easier for the studio to relax and let things happen... They're also looking at how far back they can push production without moving the release date, if any lawsuit did get a court date. Even if Bryan doesn't direct the film, he's still going to get a major payout because the deal with them was made final months ago."

The original lawsuit against Bryan Singer claims that the filmmaker and other men forced themselves upon Michael Egan, 31, when he was between the 15 and 17 years old, using cocaine and alcohol to coerce him into performing sexual acts. A second lawsuit was filed on behalf of a young man from Britain. However, the insider reveals that the filmmaker's lawyers have still not been delivered the cases yet, and that he has proof the allegations are false.

"Bryan's lawyers still have not been delivered the cases. It is being dragged out as long as possible because the plaintiff's now know that as soon as they do deliver the cases, they'll be dismissed. Bryan's lawyers have evidence to prove the dates don't match up on the first lawsuit and witnesses to prove Bryan's movements on the night of the Superman Returns premiere in London."

The director has also reportedly been "scrubbing clean" his circle of friends over the past month.

"Bryan's been scrubbing clean his circle of 'friends,' getting rid of anyone who has said anything to the press in the past month. He feels really betrayed by the people that he's been so generous to turning on him and saying awful things, which get back to him."
