'Fiddler on the Roof' Liane Hansen speaks with Jerry Bock and Sheldon Harnick who wrote the lyrics and music for Fiddler on the Roof which opened on Broadway in September 1964.
Norman Jewison was well respected as a director, thanks to In the Heat of the Night (1967) and The Thomas Crown Affair (1968), two very tough and masculine films. Fiddler on the Roof was thus a formidable challenge as it was his first foray into the musical genre. Early on in the project, Jewison determined that the film's success depended on a strong element of realism throughout the production, hence his extensive travels from Canada to much of Eastern Europe.
