A brilliant film that helped define a genre

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
