6. Army-Trained Crew, in "The League of Gentlemen" (1960)
Of course, "Kelly’s Heroes" wasn’t the first film to feature a group of soldiers-turned-bank robbers, but it’s still quite different from "The League of Gentlemen," which isn’t set during wartime. Instead the film involves former army personnel who are deemed corrupt in some way or another who are brought together to lend their specific military expertise towards a foolproof bank heist plot. We consider the plan foolproof despite the group’s ultimate downfall, and still count the job as a relative success (compared to most foiled heists in other movies) due to the very rare and circumstantial reason that they were caught.
5. Elliott Gould Takes Advantage of His Situation, in "The Silent Partner" (1978)
Pulling a job from the inside isn’t always a good idea, but Elliott Gould shows us that it can work if the inside man isn’t connected to the outside men in any way. He plays a teller who learns that his bank will be robbed, so he puts aside a whole bunch of money for himself knowing that it will just be lumped in with the real robber’s take, as far as the bank and the police are concerned. Unfortunately, the real robber (Christopher Plummer) catches on to Gould’s sneaky cut-in and threatens his life. "The Silent Partner" is apparently a remake of a 1969 Danish film with the English title "Think of a Number," so that film should get some credit for this clever plot.
