Originally an HBO special, Billy Crystal: A Comic's Line stars the eponymous Crystal essaying a never-ending stream of sharply etched characterizations. The premise of the hour-long special is that Crystal is auditioning actors for an upcoming musical. His interpretation of the many auditionees--whose talents range from slim to none--is funny enough to bring tears to the eyes. One of the best bits has Crystal portraying a small boy left home alone by his parents. ~ Hal Erickson, Rovi
