You got me thinking now....
"Mister Roberts" War CLASSIC in every way. Henry Fonda, James Cagney, William Powell, Jack Lemmon
"Kelly's Heroes" (1970) Clint Eastwood; Telly Savalas; Donald Sutherland; and Harry Dean Stanton in a hilarious World War II adventure. Great acting all around, great cinematography. Kelly (Clint Eastwood) captures a German colonel (David Hurst), who inadvertently tells him where the Germans are hiding $16,000,000 worth of gold bars. Kelly enlists the aid of his platoon to trek behind the German lines and steal the cash. FUN MOVIE!
Another funny war era movie is the Mel Brooks film "To Be or Not To Be".
Bill Murry in "STRIPES"!!!
"The Final Countdown" A United States aircraft carrier from 1980, with full compliment of nuclear weapons, jets, and crew is somehow transported back in time to December 6th 1941 by a strange phantom storm. The ship's captain (Kirk Douglas) must make a choice about getting involved in the next days attack by Japan on Pearl Harbor.
I'm not sure if cold war nuclear countdown type films are in the running, but If you can find this great 1977 film called
"Twilight's Last Gleaming", you guys may enjoy it.
From Wikipedia:
""Twilight's Last Gleaming" is a 1977 film directed by Robert Aldrich, starring Burt Lancaster and Richard Widmark. It is loosely based on the 1971 novel, Viper Three, by Walter Wager. It tells the story of Lawrence Dell, a renegade USAF general, who escapes from a military prison and takes over an ICBM silo near Montana, threatening to launch the missiles and start World War III unless the President, played by Charles Durning, reveals the real reason why America fought in the Vietnam War."
A split screen technique is used at several points in the movie to give the audience insight into the simultaneously occurring strands of the storyline.
The film included in the cast such Hollywood notables as Melvyn Douglas, Vera Miles, Joseph Cotten and Burt Young.
"Telefon". is another cold war movie from 1977, and stars the great Charles Bronson.
I don't want to say too much about this film, as I don't want to spoil anything. But it has Donald Pleasence as a renegade political or ex-KGB who has gone rogue and is activating sleeper agents in the USA without permission from Moscow. He must be stopped before these actions incite the start of World War III with the Americans. It's very dated, but lots of fun. A real guy film. With Charles Bronson, how could it be anythig but? But, it's not a war movie. It's more spy / espionage. Just save that one for the spy film night.
