Everyone talks about the 4 minute single take opening, which was remarkable for the time, but there is an even more impressive cinematic marvel that occurs about 39 minutes into the film. It is the apartment of Sanchez, the shoe clerk, and the shot runs for 5 minutes and 23 seconds without a cut. There are over 20 different camera set-ups within this one scene, smoothly flowing from one to another to another. Supposedly this was the only locale in the film that was a studio set and that helped pull off the coordination of so many elements. Considering how much exposition, character set-up, and drama is on display in this one shot, it's the real gem.
