Fail Safe (Tense, cold war nuclear drama)

Yojimbo (A Japanese foreshadowing of the Man With No Name theme soon made popular by the spaghetti western. In this case it's a ronin instead of a cowboy.)

Le Salaire de la peur (The Wages Of Fear) (The remake Sorcerer is even better, imo, but you asked for pre-70's. This is an excellent and tense movie about men hired to transport nitroglycerine through a jungle to put out an oil fire. Either version is worth seeing, but William Friedkin's remake is the version I personally prefer.)

Patton (The mighty George C. Scott at his very best. Not so much a war movie as a character study. Also the best intro to any movie ever made...)

Destroy All Monsters (Big monsters, aliens, spaceships, hidden bases....do you really need more?)
