The best part of the Fantastic Four reboot is the fact that it bombed so hard at the box office during opening weekend. With a budget of roughly $120 million, it only managed to pull in about $26 million over three days. While it may eventually break even (or turn a profit) after its international theatrical release and DVD sales, there's no telling how much more the studio paid to promote it. In short, this is a big black eye for 20th Century Fox's superhero movie record. And since this is the third failed attempt to make a movie with this franchise, Fox may decide to cut its losses and sell the Fantastic Four rights back to Disney and Marvel to make up the difference.
That's not as crazy as you might think, either. The studio's 2003 attempt to turn Ben Affleck into Daredevil panned out slightly better than Trank's Fantastic Four. But despite Daredevil's profit-earning box office, Fox's efforts to make a sequel or reboot for Daredevil hit the skids. The rights eventually reverted to Marvel, resulting in 2015's popular Netflix series of the same name. Meanwhile, Sony's Amazing Spider-Man franchise performed even more admirably in theaters, but didn't destroy box office records or win much favor with fans or critics. Soon after Amazing Spider-Man 2, Sony and Marvel reached an agreement to bring Spidey into the Marvel Cinematic Universe.
In short, it took way less failure than Trank's Fantastic Four reboot to reunite Daredevil and Spider-Man with Marvel Studios. Given what a disaster the film has been for Fox, don't be surprised to hear about an impending deal with Marvel to bring the Fantastic Four franchise back into the fold as well.
