2) Fantastic Four
Much of the blame for Fantastic Four’s failure can be laid on its chaotic production, with director Josh Trank and the studio coming to loggerheads. As Trank infamously Tweeted, it was originally a very different movie.
Fox have so far kept a tight lid on exactly what changes the film underwent, but we can fill in a lot of the gaps thanks to footage that was seen in the trailers but completely absent from the finished product. For instance, the inclusion of the Fantasticar (yes, really) and a big action scene for The Thing.
We also know that Doctor Doom was originally an anti-social blogger called Victor Domashev. Due to huge backlash from the fans, this was changed in reshoots and all references to this version of the character were removed.
