Gavin Polone is smart and snarky and Hollywood’s erstwhile bad boy. He keeps earning his nickname as the Prince Of Darkness by today filing yet another lawsuit against an entertainment company. (His now infamous lawsuit against a former talent agency employer exposed oodles of bad behavior…) This time, it’s Summit Entertainment which the manager/producer is suing for breach of contract along with the screenwriter Pablo Fenjves over the film Man On A Ledge. Polone claims he and his Pariah production company were cut out of the deal. The Hollywood Reporter‘s legal eagle Matt Belloni has details but they’re boring.
