Great movies of the 1970s
The French Connection
All the President's Men
Coal Miner's Daughter
Of course both The Godfather and The Godfather part II
Butch Cassidy and the Sundance Kid
Deliverance
Young Frankenstein
The Deer hunter
Star Wars
Jaws
Rocky
One Flew Over the Cuckoos Nest
I'd take Jaws, Star Wars and Rocky off the list of 'great movies' as they are blockbusters intent on making cash and merchandise instead of truly great movies.
Especially Star Wars. By the time it was released in 1977, I had seen Midnight Cowboy, The Godfathers and One Flew over the Cuckoo's Nest (truly great films). Star Wars was marketed as a kid's movie.
I do remember Star Wars as the first time I was called 'sir'! Context is important here. I was a sophomore in college and drunk as about seven skunks. "Sir, I must insist you leave the theater"
It was still a 'sir'!
