Christopher Walken has said his latest role was "challenging", but one he wanted to get right.
The actor stars in independent action drama The Power Of Few, which follows several stories, including a tale of a teenage boy desperate to get medicine he can't afford for his infant sibling and a story about two detectives resorting to torture to solve a crime.
Christopher plays an insightful homeless man named Doke.
He said of the part: "I hoped that I could be good in it.
"If you're an actor, you take parts as they come to you. When you read the script, you ask yourself, can I be good at it, and sometimes you're right, sometimes you're wrong."
The star said filming gave him his first chance to visit New Orleans. During breaks in shooting, he took walks in the French Quarter and watched cargo ships and paddlewheel boats on the Mississippi River outside his hotel window.
