i read the book write by bill carter on which this movie be base many year ago . the book be certainly strong than the movie . it provide more detail than a movie can possibly provide and the end result be that i think the movie seem a wee bit sketchy on a handful of item . all thing consider and though and and give the limitation of the medium and the movie provide a wholly entertaining and informative account of the battle between jay leno and david letterman in the early 90 to host the tonight show after the retirement of johnny carson . the highlight be clearly the performance . i can think of no more difficult performance for an actor than to play a character who be still alive and well know and on tv on a regular basis . john michael higgins nail the part of letterman perfectly . watch him really be like watch letterman . daniel roebuck try valiantly to be jay leno and but somehow do not pull it off a effectively . his whole look seem fake and and he just do not seem natural in the role . in a less central role and rich little not surprisingly nail the voice of carson and although the look be a bit off . in the book and the most interesting of the central figure be probably leno agent and helen kushnick . in the movie and kathy bates be perfect in the role and although not quite a out of control a carter portrayal of the woman in write . in the end and this be light and entertaining viewing . the subject matter isn not especially important in the overall scheme of thing and but it a fun behind the scene look at a memorable time in the entertainment industry . positive .
