Directors Mevlut Akkaya (Kanake) and Ron Frank (The Naked Truth) set off to research and present their findings on the birth of modern stand-up comedy, which is universally recognized to have been in the Catskill Mountains. That fabled location was the boot camp where quite possibly the greatest generation of Jewish-American comics came of age. The roster of faces providing testimony here includes Sid Caesar, Mickey Freeman, Dick Gregory and Robert Klein. Expect a real education. Opens Oct. 25 at Mariemont Theatre. (Not Rated) Not screened in time for review
