Ben Stiller has made a documentary that is a tribute to his parents, who were comedians. The documentary, which appears to be called "Stiller & Meara: Nothing is Lost", is described as a loving tribute to his parents. However, there is some confusion as one outlet mentions a different documentary title and subject, "Mel Brooks: The 99 Year Old Man!", while another outlet mentions a tribute to Diane Keaton, which may not be related to Stiller's documentary.
