Jeremy PivenJeremy Piven has slapped the Public Theater in Manhattan with a "cease and desist" letter over 'The Piven Monologues,' a comic look at the star's case of mercury poisoning and subsequent pullout from Broadway's 'Speed-the-Plow.'

Piven's attorney Marty Singer told NY Post,"We didn't say you cannot do the play, we said you can't make defamatory statements about our client." An additional performance of the show is scheduled for next month, but there is no word whether the show will go on.
