Bale suffered herniated disc during 'American Hustle' filming

Hollywood star Christian Bale apparently suffered herniated disc during the filming of 'American Hustle'.

The 40-year-old actor said he had to put on some pounds to portray an overweight conman Irving Rosenfeld in the film, reported Daily Express.

"At one point I said enough already. He lost three inches of height, and even got a herniated disc. He's a quiet, sweet, smart person with endless passion...," the films director Director David O Russell said.
