This is a terrific video with Kathy Bates absolutely hateful as Leno's manager. The actors portraying Leno and Letterman are good but try too hard to mimic rather than portray each.
The video is great at showing the behind the scenes maneuvering that allowed Leno to steal The Tonight Show from David Letterman. That may be harsh but I don't think there is any other way to describe what happened. The rightful heir to Carson was Letterman. Leno was (and still is) a poor pretender to the throne.
That being said, the intrigue and lies used to move the transfer of the Tonight Show to Leno is great. CBS's decision to enter the late night market and lure Letterman is played out realistically. It's interesting to note that if Letterman got the Tonight Show, CBS was ready to go after Leno.
The video is a good companion to the book. The book provides much more detail and inside information but the video hits the highlights. If interested, you may want to read the book before viewing the video.
Look forward to seeing this on DVD hopefully with some extras.
