I saw it for the first time only about 3 or 4 years ago. Must have watched it 10-15 times since.
I ran across Richard Widmark shooting an episode of the TV series Madigan in 1972 somewhere in the 80s on the West Side. He was about a block away and it suddenly dawned on me who he was, very distinctive look about him.
They were preparing a shot to be filmed on the street. Cameras were setup near a “pimpmobile”. This took maybe an hour, but I stood there to watch what was going to happen. Widmark stood at a distance waiting and smoking. Finally, they filmed the scene with him talking to someone in the car.
Later I made certain to watch the episode on TV. The scene which took an hour to setup and film lasted maybe 10 seconds on screen. Just damn.
