Uncredited actors
I remember noticing how Chevy Chase was uncredited in this movie the first time I saw it. I thought it was funny because it was also the most "downplayed" part I had seen him do until then. (This was not long after he had his streak of blockbuster comedies in the 80's.) Now when I checked the credits here on IMDB I saw that there are a handful of uncredited actors, some of which are very familiar faces. (Edward Herrmann, Fisher Stevens.) Makes you wonder why, huh? :-)
I'd also add that I think, like most others here, that this is an immensely underrated movie.
