 HBO movie about the behind-the-scenes network politics responsible for the changes in late-night talk-show hosts, after the retirement of Johnny Carson from the Tonight Show on NBC. Jay Leno and David Letterman were both vying for the position, but Leno s tough manager Helen Kushnick got him the spot. In the wake of her  stepping on the toes  of powerful network executives and  playing hardball  tactics with guest bookings, she found herself being pushed out of her job as Tonight Show Executive Producer and Jay s manager. Letterman, devastated by his being passed over, brought in superagent Mike Ovitz to negotiate on his behalf, resulting in his move to CBS.
