Evangeline Lilly has described Peyton Reed's version of Ant Man as more 'American' than that of Edgar Wright.
Wright was originally on board to direct the latest Marvel movie but left the project due to creative differences in May 2014.
Lilly is set to take on the role of Hope Van Dyne in the film, and says that there were obvious differences between the vision of the two different directors.
Speaking to Empire, the actress said: "I think the most defining difference between the two scripts was that Edgar's didn't take itself as seriously.
"It was fun and silly and brilliant irreverent - a romp from beginning to end, in classic English fashion. Whereas where we've gotten to is so much more American. There's tons of levity, but just as much emotion."
Ant-Man is the second of two Marvel films to hit the big screen this year and will see Reed at the helm of a Marvel film for the first time - needless to say, this is the biggest movie of Reed's directing career to date.
Rudd is set to take on the role of Scott Lang in the film and he and Lilly are joined on the cast list by Michael Douglas, Corey Stoll, Bobby Cannavale, Michael Pena, and Judy Greer.
Ant-Man is set to be another huge movie for Lilly and is the first time that we have seen her on the big screen since the success of The Hobbit: The Battle of the Five Armies at the end of last year.
Ant-Man is one of the new Marvel franchises that we are going to be treated to over the next few years - Doctor Strange and Black Panther are others that are also on the horizon.
It was announced earlier this month that we are going to see Rudd reprise the role of Scott Lang in Captain America: Civil War - filming is already under way.
Ant Man is released 17th July.
