I just went back and watched this again after many years and still find it one of the best movies ever made about movies. This "movie within a movie" has it all. Suspense, drama, comedy, great and numerous cameos, and some "inside Hollywood" jokes. One highlight is at the start where the actors are describing the best long opening tracking shots of all time while Robert Altman skillfully is showing you one at the same time! The Burt Reynolds cameo is very funny, sounds unscripted, and is one of many brilliant uses of this device. Favorite line: "waiter, this is a wine glass. I'd like my water in a water glass". The line comes from Tim Robbins, who is excellent as studio executive Griffin Mill.
