The Spanish Prisoner 

I took David Mamet's Spanish Prisoner from the library thinking that I had not seen it before, turns out that I had, but except for a few scenes I couldn't recall anything, not the plot or the story. That was good because Spanish Prisoner turned out to be quite an intriguing entertainer. The plot thickens at every new scene and you are caught up in the mystery. It stars Campbell Scott as the hero and for a change, Steve Martin as the villian. David Mamet's wife Rebecca Pidgeon also has an interesting role in the film. Worth watching if you haven't seen it or have turned amnesiac like me.
