Richie Moriarty, cast member of the CBS show Ghosts, should be in Montreal this month beginning the filming of the third season of the show. Instead, production has been delayed as the Alliance of Motion Picture and Television Producers failed to reach a resolution with writers and actors on strike the past two months. Moriarty, 43, a Thomas S. Wootton High School graduate, is part of that strike, which he says comes at a critical time for those in the acting profession.
