According to Reuters, the leading man said that the part made him a better actor.
"I've changed. My concepts have changed. Everything I've done up until now has been an apprenticeship," he said.
"Now, I think, at 32-years-old, I've garnered enough experience to know what I don't want. Now, I know what I do want."
He credited his character's manipulative nature with giving him the right acting challenge to take his career to the next level.
"I must psychologically put everybody on edge, that is an art and I've had to learn that over time," he added. "And as he gets older, you see more of the internal struggle inside him."
