An excerpt from the book The Story of Marvel Studios: The Making of the Marvel Cinematic Universe has revealed a shocking fact that Ant-Man and the Wasp director Peyton Reed had "headaches" whenever he had to shoot the film with the leading actor Paul Rudd of the film because studios two other blockbusters Avengers: Infinity War and Avengers: Endgame was also being filmed at the same time and the director often had to reschedule the filming, but later on as the time passed Reed himself clarified that the thing eventually got better and sort out.

"We were shooting our movie, in which Paul is the main character. He is Ant-Man," Reed says in the book. "But that stuff was sorted out because the Avengers movies shot for months and months and months. So they were able to around us, which was great."

"We did not know for a long time how we were gonna deal with it, because [Infinity War] is the biggest dramatic move in the entire MCU," the director added.

"At the end end of the third act," Reed explained. "We almost wrap all the characters up into a neat bow: They have rescued Janet. Hank and Janet are back together. Scott and Hope have resolved their things. She's a fully-formed hero. Everybody seems great. and then that tag scene came along, and we pull the rug out from the audience and we trap Scott in the Quantum Realm."
