“The pleasingly insouciant revival of David Mamet’s anti-Hollywood screed ‘Speed-the-Plow’ was one of the few shows on Broadway this fall to actually attract an audience. … That’s why the news of star actor Jeremy Piven’s premature departure (he says he suffers from abnormally high levels of mercury, because of a diet heavy in sushi and Chinese herbs) from ‘Speed-the-Plow’ this week caused such an orgy of self-serving consternation. Everybody was about to make money.”
