This is one of the most compelling films I've seen in a long time. I wasn't sure if I was in the mood for a serious "psychological thriller" but this movie held my rapt attention until the very end. A brilliant example of just how talented Robert Altman is as a filmmaker. While most people pigeonhole him as "that guy who makes the movies with the large ensemble casts and lots of overlapping dialogue", this movie finds him working with a cast of six, and most of the action takes place within the heroine's head. Beautiful (of course) photography by Vilmos Zsigmond is just the icing on the cake. Don't miss this forgotten treasure by an American master.
