The dispute between the Broadway producers of "Speed-the-Plow" and Jeremy Piven is officially on to its next act -- arbitration.
In a statement, the show's producers said Wednesday that the case would be heard June 8 and 9 in New York by George Nicolau, a professional arbiter. It follows a grievance hearing held last month at Actors' Equity Assn. in which a committee composed of five Equity members and five members of the Broadway League, which represents the producers, did not resolve the dispute.
Piven abruptly left the revival of the David Mamet play in December after his doctor said he was suffering from mercury poisoning after eating too much fish over a lengthy period of time.
In response, Piven spokeswoman Samantha Mast, said in a statement that the actor was looking forward to testifying at the arbitration.
