20. Megan Fox Was Too Fiesty For Her Director
Megan Fox was a relative newbie on the acting scene when she landed a hit role in the action-packed Transformers alongside stars like Shia LaBeouf. This performance put the model on the map and she even gained the title of "the most beautiful women in the world."

Yet, her good looks were not enough to keep her out of bad media press. The Transformers producers fired the actress because of certain inappropriate comments made toward the director. Her role was filled by model Rosie Huntington-Whiteley and Miss Fox never really gained an equally impressive stint again.

18. Katherine Heigl Made Too Many Enemies In Hollywood
She is the queen of the big and small screen with amazing performances in films like 27 Dresses, The Ugly Truth and Life As We Know It. So one wonders how Katherine Heigl managed to lose her good girl fame. In fact, she is also an Emmy Award-winning star thanks to her role as Izzie Stevens on Grey's Anatomy.

The trouble comes due to her inability to keep her negative opinions quiet. The actress has become known for bad-mouthing film and TV projects when she does her interviews. She repeatedly speaks down about several shows and this offends producers... Consequently, she isn't landing as many new jobs these days.
