Ant-Man” is now “a little bigger, a little more aggressive” thanks to Adam McKay and Paul Rudd.

McKay talked to Collider about the new “Ant-Man” screenplay, which he teamed up with star Rudd to rewrite after director and co-writer (along with Joe Cornish) Edgar Wright abruptly left the project due to creative differences with Marvel. McKay ultimately decided against stepping in as director, leaving that chair for Peyton Reed to fill, but did sign on as co-screenwriter.

According to McKay, he and Rudd, whom he directed in “Anchorman” and its sequel, “holed up in hotel rooms” and “did a giant rewrite of the script” in six to eight weeks.

“We just shaped the whole thing,” McKay told Collider. “We just tried to streamline it, make it cleaner, make it a little bigger, a little more aggressive, make it funnier in places.”

McKay also said the duo added action sequences, which amount to half of the film’s total beats.

“We added some new action beats,” he said. “I grew up on Marvel Comics so the geek in me was in heaven that I got to add a giant action sequence to the movie. I was so excited. So we did; we added some cool new action. There’s a lot that’s already in there from what Edgar did, there’s a lot of dialogue and character still in there.”

The Marvel pic also stars Evangeline Lilly, Michael Douglas and Corey Stoll. It storms into theaters on July 17.
