As far as I can tell this promo for The CBS Friday Night Movie is from September of 1976. Curiously, it seems that three of the five movies previewed were actually broadcast on Wednesdays:
Chinatown – Wednesday, November 17th, 1976 Paper Moon – Friday, October 1st, 1976 Save the Tiger – Wednesday, December 8th, 1976 Play It Again, Same – Friday, November 5th, 1976 Juggernaut – Wednesday, November 3rd, 1976
I have been unable to find a list of all the movies broadcast by the network as part of The CBS Friday Night Movies. The movie block ran from 1966 to 1975 and then again in the fall of 1976.
