Joan Rivers: A Piece of Work. (2010)

Documentary chronicling a year in the life of the foul-mouthed comedy dinosaur. Living life in "the business" and what that does to a person has rarely been displayed so vividly. At age seventy five, her mental sharpness and physical stamina are astounding: You can see her mind racing as she waits to go on stage, and later she disposes of a heckler like she's stamping a cockroach. Years of fighting to be heard and taken seriously have left her tough to a fault. What's left is what you see: her mask of a face, raspy voice, and eyes that shoot daggers. She may live well past one hundred.
