I remember watching this film in 1998 at the theater and it became one of my favorites ever since. I have since watched every Mamet film I ran into, they were very good, but I believe this one's his best film yet. The story follows Joseph Ross (Campbell Scott), a salaried mathematician who's invented some truly valuable system that will make a fortune for his company. We meet him as he goes on vacation and befriends with a seemingly multi-millionaire who calls himself Julian "Jimmy" Dell (Steve Martin). Ross is then drawn into a big conspiracy surrounds his valuable "system". I won't go into the details so that i won't spoil the surprises and there are many. All the actors involved gives their best, most notable are Rebecca Pigeon as Susan, Joseph's pretty and sophisticated secretary and for Steve Martin, who was very refreshing to see in a serious role. The film has some unique and intelligent dialogs often appear in David Mamet's works. The twists are very surprising but MAKE SENSE, something that a lot of film makers have to learn these days. Overall an intelligent gem of a film you will not forget easily. Thumbs up and 10/10. Highly Recommended.
