Eric Roberts has joined the cast of "Batman Begins" sequel "The Dark Knight". The star, the older brother of Oscar-winner Julia, will be playing a mob boss in the Christopher Nolan-directed movie which is currently filming in Chicago.

Things are going well for Robert's at the moment - as well as landing the "Batman" job he's also recently joined the cast of small screen smash "Heroes", a job he's thoroughly enjoying as he told the LA Daily News that "It's a blast to walk into a hit show with none of the pressure of making it a hit."
