9. Megan Fox
Megan Fox got her big break in the hit 2007 film Transformers, but when it was time to film the sequel Transformers: Revenge of the Fallen, director Michael Bay ordered the actress to gain 10 pounds for the role. In a 2009 interview with Wonderland Magazine, Fox stated, “He wants to be like Hitler on his sets, and he is.” Bay wasn’t upset with the comments, but Steven Spielberg, who is the executive producer on the Transformers films, wanted her gone. She was replaced by Rosie Huntington-Whiteley for the third Transformers film, but Fox and Bay did work together again for the Teenage Mutant Ninja Turtles films.
