When Edgar Wright left ‘Ant-Man’ over creative differences in May 2014, fans were disappointed to hear that the filmmaker’s nearly ten years of work was going down the drain. Marvel Studios then brought in Adam McKay to work with star Paul Rudd (who actually has some popular writing credits to his name) and new director Peyton Reed on a new draft of the script. However, reports later surfaced stating that elements of Wright and Joe Cornish’s script remained intact. Now, we know exactly which parts stayed the same.

While speaking to Uproxx about his upcoming Phase Two finale, Reed discussed the changes made to Scott Lang and Hank Pym’s introduction into the Marvel Cinematic Universe. First, he started by sharing the core ideas from the original script that stuck around:

“I read all of the existing drafts that Edgar [Wright] and Joe [Cornish] wrote. It was clearly Edgar and Joe’s idea to make this a heist movie and to sort of loosely base it on Marvel Premiere ‘To Steal an Ant-Man’ that introduced Scott Lang. It was also their idea to create this Hank Pym/Scott Lang, mentor/mentee relationship. And, also, their idea to kind of do a Marvel movie where the third act battle take place in a little girl’s bedroom. Genius. It was great.”

Reed went on to talk about the changes that he, McKay, and Rudd made when it was their turn to tackle the biggest little hero in the MCU:

“Well, I came on about the same time that Adam McKay and Rudd were doing rewrites. And I’ve known McKay for some time and we talked on the phone and we were both really jazzed about the idea of, in the third act, in a movie in which we will have seen shrinking a bunch, let’s take it even further in the third act and introduce what, in the comics, was the microverse, in what we call the quantum realm. Creating this moment of self-sacrifice where he has to go into the quantum realm to save his daughter, that was something that was never in those drafts that Adam and I brought to it.”

By the sounds of things, ‘Ant-Man’ remains largely untouched from the time it was in Wright’s hand. Sure, it’s not exactly the same since he’s not helming the project anymore, but it sounds like Reed and company have injected some pretty cool parts from the comics into the film. We’ll see how well the two visions harmonize next week. Until then, let’s hear what you think about Marvel’s next big/little thing.

‘Ant-Man’ starring Michael Douglas, Paul Rudd, Evangeline Lilly, and Corey Stoll marches into theaters on July 17, 2015.
