The Over the Hill Gang
The Gang That Couldn't Shoot Straight
The Public Enemy
What Did You Do in the War, Daddy?
The Hasty Heart (stars Ronald Reagan, by the way)
The War Game
The Evil That Men Do
The Wyoming Kid
The Horizontal Lieutenant
Or we might think of a film with appropriate themes:
Dr. Mabuse: Der Spieler (The Gambler)
The Paths of Glory
Dr. Strangelove -- wait, that's taken!
I have to stop myself or I'll use up the obvious ones. You get the idea. Any suggestions?
