10 Shocking Reasons Actors Quit Movies

10. To Work On A Flop Comedy Instead - Katie Holmes (The Dark Knight)

Following the success of Batman Begins, it was simply assumed that the ensemble cast would return in its entirety for the much-anticipated sequel The Dark Knight, though there ended up being one major exception - Katie Holmes.

Holmes, who played Bruce Wayne's (Christian Bale) love interest and Gotham's assistant district attorney Rachel Dawes opted not to appear in the follow-up, deciding instead to co-star in the crime comedy film Mad Money, reportedly due to her deep desire to work with legend Diane Keaton.

Now in fairness, Holmes had no idea that Mad Money would be a critical and commercial flop, but even so, turning down a mega-budget Christopher Nolan blockbuster to star in... Mad Money? 

It seems like a completely baffling career choice on paper, especially given the meatiness of Rachel's role in The Dark Knight.

To add insult to injury, Holmes' performance in Mad Money was singled out as especially weak by numerous critics, while many reviewers of The Dark Knight deemed Maggie Gyllenhaal an "upgrade" over Holmes. Yikes all around.
