Such a good film. It's one of a short list of films that I keep on my iPad for long flights and can watch over again at the drop of a hat. The tone, the dialog, and the casting all work so well. I don't know how well-known the actors in it were at the time, but for me it actually works better that they're not know very well-known (at least to me)--it helps preserve the suspension of disbelief not to be looking at Al Pacino or Sean Connery and trying to forget who they are. (Of course, that said, one of the other movies on my iPad is 'Hunt for Red October', so...)
