I almost didn't see this movie. I didn't really want to, but my dad rented it and so I watched it. I had no clue about the plot or even who was in it other than Steve Martin who is really good. I was ignorant and I think that helped me like it. At times, especially the first half hour, the movie is really slow, but please stay with it. The last forty or so minutes are filled with so many twists and turns it will leave you smiling with joy. So few films have the guts to challenge the watcher to keep up and figure it out.
Sorry folks, no plot points given. But I highly recommend The Spanish Prisoner. I give it a B+.
