The 29-year-old actor's 'War Dogs' director Todd Phillips recently said Teller looks like "almost as if he doesn't have to try" but the actor seems to disagree with him.
"It's frustrating when people say that because an actor's greatest tool is his preparation and I've always felt like I do as much prep as anybody," Teller told The Observer Magazine when asked about Phillips' comments.
Teller and Jonah Hill, 32, star in the real-life inspired drama about two stoners who won a USD 300 million contract with the Pentagon to supply US allies with arms in Afghanistan.
