Director Michael Bay claims he was not offended by the jibe that he "wants to be like Hitler on his sets", but producer Steven Spielberg was reportedly outraged.
The Hollywood legend demanded Fox be dumped from Transformers 3: Dark of the Moon over the comment, made during a 2009 press interview.
The Mirror reports that ahead of the film’s July 4 premiere, Bay has revealed he was told to get rid of the 25-year-old star.
"You know the Hitler thing?," he was quoted as saying.
"Steven said: 'Fire her right now.'"
Fox appeared in the first two Transformers films, and was soon after named one of the sexiest women in the world. She claimed she left the third in the series to pursue other opportunities.
She was replaced by British model Rosie Huntington-Whiteley.
