When Edgar Wright left ‘Ant-Man’, a number of directors were brought up as a potential replacement. Among the names were ‘Anchorman’ and ‘ Step Brothers’ director Adam McKay, but due to an already busy schedule, he passed on the opportunity. However, he did stick around to do a rewrite of the script for Peyton Reed to helm. Previously, we weren’t too sure how much McKay added and subtracted from the upcoming Marvel movie, but now we have a small inkling of an idea thanks to a recent interview.

While speaking with Collider to promote the short film series ‘We The Economy: 20 Short Films You Can’t Afford To Miss’, McKay briefly spoke about the ‘Ant-Man’ situation and the part that he played in it all. After confirming reports that it was indeed his schedule that kept him from the director’s chair, he revealed that he worked on his rewrite with Paul Rudd over the course of six to eight weeks. And while he mentions keeping a lot of what Wright contributed to the script, McKay says that they added “some new action beats” and made the story “a little more aggressive”. To hear everything that the filmmaker had to say about his contributions to the Phase Three feature film, check out the video below:

Armed with the astonishing ability to shrink in scale but increase in strength, con-man Scott Lang must embrace his inner-hero and help his mentor, Dr. Hank Pym, protect the secret behind his spectacular Ant-Man suit from a new generation of towering threats. Against seemingly insurmountable obstacles, Pym and Lang must plan and pull off a heist that will save the world.
