Yahoo reports that is why Megan Fox was fired from "Transformers 2":
According to a new Michael Bay oral history in GQ, Bay says Fox was booted by the direct order of Sir Spielbergo (who helped produce the movie).What height issue? Adolf Hitler's height was 5 ft 8 in (173 cm), and Napolean was 5 ft 7 in tall. Both were about the same height as Justin Bieber and Tom Cruise.
"She was in a different world, on her BlackBerry. You gotta stay focused. And you know, the Hitler thing. Steven [Spielberg] said, 'Fire her right now.'"
"The Hitler thing" was Fox saying Bay ran his movie sets "like Hitler," which probably didn't sit well with Spielberg. It's a shame: She should have just run with her Napoleon comparison, which is far more apt, save for the height issue.
