Dying to Do Letterman (2011)

When 35 year old stand-up comedian Steve Mazan learned he was dying of cancer, he dedicated the rest of his life to making his dream come true: performing comedy on The Late Show with David Letterman. This documentary chronicles his five-year journey, as he races his own ticking clock to achieve a nearly impossible goal. Hilarious and heart-breaking, Steve brings a brand-new perspective to living with cancer. This is a story that proves it's not how much time you have, it's what you do with it. As Steve says, 'If you stop chasing your dreams, you're already dead.'

Unfortunately the movie Dying to Do Letterman is not yet available on HBO Max.
