I lived in NYC in the 1980s, and one day when my cousin was visiting, circa 1984 - 1985, we walked into a film shoot in Manhattan - I think it was on 8th Avenue, maybe around 50th Street. We were told that it was "Back to the Future". It seemed as if it was quite a complex operation, too, with streets roped off and cameras. Filming dates coincide, but there is no mention of this particular filming location; they are all on the West Coast. Can anybody verify this? Thanks very much!
