Why isn't this movie talked about more? It's very well made, has top notch performances, and an awesome jazz score. It seems like it's been forgotten though, even by Altman fans, and that really bums me out. Kansas City may not be Altman's absolute best movie, but it certainly ranks among his better ones, and I would highly recommend it.
The stars of the film were the musicians, as Altman did a wonderful job putting together a band of young jazz musicians (at the time) who took on the personalities of the Kansas City greats, including Lester Young and Coleman Hawkins. The movie itself appears aimless, which was probably as Altman intended, but he does create a strong sense of time and place.
