Oscar-winner Adrien Brody owes his success to his poor upbringing, because it taught him credibility is more important than money.

The Pianist actor grew up in Queens, New York City, but is grateful for his underprivileged start as it taught him not to crave material possessions.

And while he acknowledges the appeal of a film star lifestyle, he insists artistic integrity is more important to him.

He says, "I grew up without a lot of money and my parents grew up with far less money. And that's kept me in line. Really in line.

"It means I don't have to do s**tty movies to support my material habit.

"I would have loved to make a lot of money as an actor. I would have loved to not live in a s**tty little apartment for most of the time I've been in Los Angeles. I would have loved to have nice things and bought new cars, but it's painful for me to do a bad role. Personally painful. You feel like you're lying to everybody.

"It's just not worth it."
