The Transformers franchise served as a breakthrough for actress Megan Fox, but she absolutely hated working with director Michael Bay, and the two feuded during production of the first two films.
Asked whether she would return for the third film, Dark of the Moon, Fox answered, “Sure. I mean, I can’t sh*t on this movie because it did give me a career and open all these doors for me. But I don’t want to blow smoke up people’s ass. People are well aware that this is not a movie about acting. And once you realize that, it becomes almost fun because you can be in the moment and go, ‘All right, I know that when he calls Action! I’m either going to be running or screaming, or both.’"In subsequent interviews, Fox told reporters that Bay's treatment of her was demeaning and misogynistic. She claimed that part of her audition for the role involved being filmed while washing his Ferrari. Fox hated working with Bay so much that she even went so far as to liken him to Adolf Hitler. Fox said that Bay tried to “create this insane, infamous mad-man reputation. He wants to be like Hitler on his sets, and he is. So he’s a nightmare to work for.”
After those comments, Fox was unceremoniously booted from the series. She and Bay buried the hatchet, however, and she ended up playing April O'Neil in the live-action Teenage Mutant Ninja Turtles movies produced by her former director.
