Christian Bale

The 'Dark Knight' star had no formal acting training and explained that he ended up in the profession by chance.

Bale said in an interview with NJ: "I never took acting lessons or anything.

"It was more of a case of me just being interested in each thing as it came along, rather than thinking this was something I wanted to make a career of.

"But when I decided I did want to make a career of it, it didn't shock my parents. What would have shocked them was if I wanted to put on a suit and go 9 to 5."
