Christian Bale's responsibilities as a father prompted him to rethink his role in Michael Mann's Enzo Ferrari biopic.
The Dark Knight star was cast as the legendary Italian car manufacturer and racing driver last year, but the part required Bale to pack on the pounds to accurately portray him.
The British actor has previously tested his health for roles by losing and/or gaining weight for The Fighter, The Machinist and American Hustle, but this time, he decided it was too much and walked away from the project in January.
Bale has opened up about his concerns, admitting his advancing age means his body can no longer tolerate drastic changes to his waistline.
"I'm just getting older," the 42-year-old told The Associated Press. "I could lose and gain so much weight before and didn't feel any different. I just felt invincible."
