Edgar Wright's Ant-Man

While Marvel keeps a tight lid on all of its productions, there are moments in which it’s revealed that, in the end, what matters the most is the money a movie makes and not what the fans would like to see. This is the case of Edgar Wright's Ant-Man, a movie for which the director fought. In the end, he did manage to obtain an okay from the studio.

However, Edgar Wright was forced to leave the project over creative differences, and was replaced by Peyton Reed. The script he wrote was rewritten, although some of the scenes Wright had written were kept.

Edgar Wright left because Marvel's Creative Committee wanted more MCU Easter-Eggs, as well as more scientific gibberish over the Pym particles. He left, despite Joss Whedon’s comment that his script was not just the best MCU script, but also the best Marvel script in the MCU.

It's a shame, really, that this Ant-Man didn't happen.
