It has been a long time since I've seen this movie. I'm quite sure many have seen this as a very bad comedy movie. For some reason when I was much younger it kept me entertained, then I quickly forgot all about this movie.
Weird Al Yankovic looks a lot weirder than he actually does today. In fact you'll see that on the DVD. He hosts the deleted scenes on this two sided DVD and you'll see the modern him fooling around in the menus before you start playing the movie.
Just think for a second. In the movie he had a curly afro and a mustache. Today he has a Howard Stern look with long hair but no mustache. He doesn't even wear glasses like he did back in the late 80s. In fact as you watch the deleted scenes on the DVD he will note that he looks different because UHF was released 13 years ago.
Long story short this film is about an unlikely TV station managed by a man (Weird Al) with a vivid imagination who is unable to keep a job. Somehow he is able to bring his station to number 1 in the ratings. He saves his station by paying off his uncle's debt while fighting a much more powerful corporate competitor station. All the while the man gets his girlfriend and declares that she will be apart of all of his dreams.
The movie doesn't have to be all that good in some respects. Suspend some belief and have fun is the order of the day in this movie. So by all means have fun because this movie isn't that bad.
