Los Angeles: Actor Miles Teller finds it "frustrating" when people call his acting effortless. The 29-year-old actor shared that he prepares extensively for each role he takes on, so when his 'War Dogs' director Todd Phillips said it is "almost as if he doesn't have to try", Miles Teller was not impressed.
