Ah, I forgot to mention " The Creature From The Black Lagoon "!!

The Loved One
The Searchers
Dr. No
Who's Afraid of Virginia Woolf
The Apartment

"The Magnificent Seven"

Dr no.

From this tread I shall source all my future movies..

The President's Analyst

I somehow thought that was a 70's movie but double checked and it was 67.

The African Queen

I'm amazed no one mentioned that. One of the best movies of the 50's. By far the best acting Katharine Hepburn ever did and the best Bogart did in the 50's (though you should also watch The Caine Mutiny).

The ones others mentioned that I really liked:
The Good the Bad and the Ugly
High Noon
Lawrence of Arabia
The Bridge Over The River Kwai

Other very powerful movies of that period:
The Birds
King of Hearts

I also suggest
Paint Your Wagon
The Americanization of Emily
Chayefsky was a great writer, but all of his TV work and most of his movie work was produced badly or acted badly. The above two plus Network (1976) were the only times his writing got the acting and production it deserved.

I tend to like examples of really brilliant acting even if the rest of the movie isn't up to it. Re watch Mary Poppins (1964) and pay attention to Dick Van Dyke. That is one of the most impressive examples of acting in the history of movies, well up there with James Coburn in the President's Analyst or Peter O'Toole in Lawrence of Arabia.

I don't normally like the kind of bash-you-over-the-head-with-a-social-message (and unrealistic characters) movie that Sidney Poitier did so many of. But To Sir, with Love was so well acted (by so many of the cast) that it should be on the list of great movies of the 60's.

I really thought there should be a John Wayne movie on there, so I reviewed a list of John Wayne movies from the 50's and 60's. Unfortunately, Big Jake was 1971 and everything John Wayne did in the 50's and 60's seems to me pale compared to Big Jake.

I feel compelled to disagree with
2001: A Space Odyssey
Forbidden Planet.
If you liked those, you just don't know what good science fiction is. Planet of the Apes wasn't as bad as those two, but I certainly don't think it was one of the great movies of the 50's and 60's. I'm sure there were a few good science fiction movies in the 50's and 60's. I'm just failing at the moment to remember what they were. Silent Running was 1972 (and a great movie that would be on this list if it had been a few years earlier).

The Guns of Navarone

"True Grit" (1969)

"Ocean's 11" (1960)

"The Cincinnati Kid"

"The Hustler"

So shall I (for Hollywood flicks that is).

"They shoot horses don't they" very well crafted movie that slowly builds up the tempo in what is basically a known story and one set.

"Butch and Sundance" just for one shot (the one where redford shoots bad guys and they fall backwards off a cliff in slow mo).

Non Hollywood.
7 Samurai,
Garm Hawa (Hindi). A really great portrayal of the struggle of one man's loyalty to the idea of free India. Great last scene where Balraj Sahni removes his old identity and jauntily sets off to join the mainstream.

OK

Lawrence of Arabia (which was already mentioned once). I used to go to the NUART in West L A. I went in there one night to find Charleston Heston. He gave a little intro. He had passed the part down which made O'Toole a monster star.

One more- Paul Newman in HOMBRE

I think O'Toole made Lawrence of Arabia a great movie, rather than Lawrence of Arabia made O'Toole a great star.

There are so many of these stories about an actor who turned down a role that made some other actor great. We can't know what the movie would have been with a different actor. Maybe it would have been a different kind of great movie. But in most cases it is clear that what DID in fact make the movie great could not have been there with the other actor.

Charlton Heston as Lawrence? Glad he turned it down.

If one watches old moves. Pay attention to the stunt work. It is usually exceptional.

It was one reason I liked Taras Bulba. The stunt work was very good.

Yeah? Have you ever seen The Incident (1967; starring Tony Musante)??? It doesn't sound like much to read about it...but DARN! I can enjoy it now, for it'sw great stars and nostalgia- but the first few times I watched it [starting back in the 80's] it was the only movie that really ever profoundly bashed me over the head.

No, I missed The Incident.

I agree with the person who suggested The African Queen.

I would add to my list, Bad Day at Black Rock. Spencer Tracy comes to town and all heck breaks loose. And he's just the catalyst.

Plus Inherit the Wind, which is still relevant today, at least in the States.
