I have see both 'The Last king of Scotland' in which Whitaker has done a commendable job but Dicaprio's portrait as Billy Costigan an undercover cop who is assigned to infiltrate the mob syndicate run by gangland delivered an astounding performance and showed a gritty side to his character. In fact, he was so good that Nicholson didn't act him off the screen when they shared screen time together. If this cannot get him a Golden Globe leave along an Oscar I don%u2019t know what would.
