When comedians get laughs, they are said to have "killed." When they don't, they've "died." In John Zaritsky's Leave Them Laughing, a California-based Canadian comic faces her death as she lived her life, "killing" her audiences. An accomplished singer, songwriter, musical comedian and parodist, Carla Zilbersmith is given the ultimate bad news. Diagnosed in 2007 with Lou Gehrig's Disease and given less than four years to live, she will leave a teenaged son, fans and adoring students. Leave Them Laughing is a 90-minute "pre-mortem" of a life lived fully, but far too fast. For Oscar-winning documentarian Zaritsky - director of the controversial film The Suicide Tourist - it's a switch in theme from the right-to-die, to dying right. 53 minute version available as well.
