Speaking at Collider’s special IMAX screening of the second Ant-Man movie earlier this week, Reed said: “I do know the rules as much as they pertain to our specific story.
“I also know what time and space can do down there and the seeming sort of infinite quality of the Quantum Realm. We talked a lot about what our movie’s internal logic was going to be for the Quantum Realm.”
“Janet Van Dyne is clearly not wearing her Wasp suit down there. There are little vestiges and pieces of it she’s taken from her suit thirty years later, but she has this spear things and these other items that feel like it’s from some sort of culture.
“There’s something going down. It’s not just some wasteland.”
Reed continued: “The coordinates she gives for them to meet her are in this area called The Wasteland, which, let’s say you were to shrink down and go Quantum, you have to go past this Quantum Void, which is where Scott sort of reached in the first movie and blacked out.
“And in this Quantum Pod, Hank is sort of able to hit the thrusters and go further past the void and penetrate this membrane into the Quantum Realm.
“And that’s the highest level, and that’s where she’s agreed to meet him. “There is definitely a shot as Hank and Janet are blasting out of the Quantum Realm where it appears there might be some sort of civilisation down there.”
He added: “There’s definitely a specific backstory to what Janet Van Dyne has been doing the past thirty years… There’s some great food down there, guys.
“The food scene in the Quantum Realm is not to be believed [laughs]. For the breathing, Janet makes the point that her time down there has not just been adaptation.
“It’s also been evolution, and maybe she’s evolved as a being. So when she’s first down there, it’s easy to imagine she survived from her suit, but perhaps things have happened from her time down there where she’s adapted and possibly even evolved.”
Avengers Endgame will be released in UK cinemas on April 26, 2019.
