Edgar Wright, known for directing acclaimed films such as Shaun of the Dead, Hot Fuzz, Scott Pilgrim vs. the World, Baby Driver, Last Night in Soho, and The Running Man, was originally attached to direct Marvel’s Ant-Man.
However, Wright chose to step away from the project when he realized his vision for an original film did not align with Marvel's desire for a story that fit within their established cinematic universe. Although Marvel kept much of his script, the studio hired a director more willing to follow their direction.
“You’re not still losing sleep over that, are you?”
Wright responded humorously about his departure from the Marvel project. He emphasized,
“I didn’t regret my decision to leave at all. I had started working on that film long before even Iron Man came out. By the time it came around, they had established the brand, the continuity, and even a certain way of making a movie. So the chance to do something really different was going away.”
Since then, Wright has intentionally avoided the superhero genre.
Edgar Wright walked away from directing Ant-Man due to creative differences and remains confident in his decision, having pursued diverse projects outside the superhero genre.
