Disney's press release for the new Ant-Man teaser trailer reveals that the official "screenplay by" credit for the movie goes to Adam McKay and Paul Rudd. We found out last year that the duo had worked together on a rewrite for six weeks, adding a "giant action sequence" and making Ant-Man "a little bigger, a little more aggressive, and funnier in places." It's clear now that this was a full rewrite rather than small alterations, a scenario which isn't all that different to when Joss Whedon rewrote Zak Penn's screenplay for The Avengers. Just like Penn, Wright (and Joe Cornish) will receive a "story by" credit, with Wright also named as an executive producer. That title is largely meaningless of course as Stan Lee receives the same credit on the Marvel movies but has zero involvement in them. What do you guys think about these behind the scenes changes to Ant-Man?
