MOVIE REVIEW
Joan Rivers: A Piece of Work (2010)
Seth Keal/IFC Films
If there’s one conclusion to be derived from Ricki Stern and Anne Sundberg’s documentary about Joan Rivers, it’s this: The 77-year-old comedienne really is “a piece of work.” She’s also — “Joan Rivers: A Piece of Work” makes clear — much more than the sum of her polarizing public image. Beyond the plastic surgeries and the abrasive demeanor is a driven, passionate woman who’s achieved the miracle of retaining her show business relevance for more than four decades.
