Making my way through old shots for other projects often results in finding stuff I had completely forgotten about. Before we lived in the Bay Area, I was there for some other reason. I was down near the water and there was a film crew working on a production of some sort. The character was on a dock and was approached by some other guys at which point he falls into the water. There was a diver that got set up in the water beforehand for safety purposes. Then they filmed the sequence. I don’t recall them doing it more than once which made it easier than drying the guy off and giving him fresh clothes, I guess!
