According to The New York Post, the ongoing arbitration between Jeremy Piven — who left a production of Speed-the-Plow last winter after citing mercury poisoning from too much sushi — and the show’s producers is reaching its final stage in New York City this week. Producers want Piven to pay after the show suffered a dive in ticket sales following his abrupt departure. (His role was eventually filled by William H. Macy, whose presence eventually stabilized ticket sales.) The notorious fracas was originally brought to the Actors’ Equity union in February, but officials couldn’t reach a unanimous verdict, which kicked it to these further, more in-depth hearings. The arbiter has 30 days to reach a decision.
