"It's not terrific. It's tiresome." So concludes hotshot producer Joseph Levine in Albert and David Maysles' classic 1961 cinema verite documentary Showman, which received a rare screening last night at New York's IFC Center, concluding its annual "Stranger than Fiction" series. The hustling entrepreneur whose ferocious penchant for movie marketing forms the centerpiece of this intensely provocative work represents a dying breed. "As I look at it now, I think, 'Why spend so much time with a guy whose actions are not to be emulated?'" reflected Albert Maysles, the seventy-two year old surviving member of the filmmaking duo, during a post-screening Q&A.
