The production began preview performances on October 3, 2008, and opened on October 23, 2008; the play was due to run through February 22, 2009. After Piven missed several performances, on December 17, 2008, Piven's representation announced that due to an undisclosed illness, Piven would be ending his run in the play effective immediately. The illness was revealed to be hydrargyria, a disease caused by exposure to mercury or its compounds, though the source is unknown. Rumours have indicated that the high level of mercury could potentially have been caused by Piven's habit of consuming fish twice a day for the past 20 years. An alternative explanation is that the herbal remedies Piven was taking were responsible for his high levels of mercury. Mamet joked that Piven was leaving the play "to pursue a career as a thermometer." On September 1, 2009, Piven, in a guest appearance on the Late Show with David Letterman, explained that he had given up red meat and poultry, and had been getting all of his protein from fish for the past 20 years. On August 3, 2009, Piven guest hosted the WWE Raw wrestling program. In August 2011, he stated he was interested in portraying the drummer from the Who, Keith Moon.
