UPDATE: I received a phone call earlier this week that UTA on Tuesday fired actor Michael Pitt who plays Jimmy Darmody on the HBO series. “If you decide to post about someone (probably WME) signing Michael Pitt, who is one of the stars of Boardwalk Empire, please note that UTA fired him as a client yesterday because he’s really difficult on set and otherwise.” I felt that Pitt was too small a name to bother posting this bad news (I’d never heard of him) or that he had landed at WME. But since the news of the WME signing is now out there, I thought Deadline readers deserved to have the complete story. I understand that UTA agent Billy Lazarus spent “many years” making Pitt into a working actor. So it’s safe to assume that Pitt must have really pissed off the agency big-time.
