The Last Time I Saw Archie

The Last Time I Saw Archie is a 1961 comedy film set in the waning days of World War II. Robert Mitchum stars as Arch Hall Sr., a lazy, scheming American in an aviation school for pilots too old to fly aircraft but not too old to fly military gliders and liaison aircraft. Jack Webb produced, directed and costarred.

As time goes by, Bill comes to suspect that Cindy is a Japanese spy, but he cannot get Archie to take it seriously even though Cindy keeps giving him money in outsized old bills. It turns out that Cindy actually is a spy, but for American counterintelligence, despite the opposition of her guardian, Colonel Edwin Martin, the base commander. Sergeants Erlenheim and Greenbriar get into trouble when they break down the door of her apartment, thinking they will catch her in the act of reporting to the enemy, only to find her presenting her findings to Martin.As the war winds down, requirements change and the trainees are given the choice of retraining to become either gunners or glider pilots. Archie and Bill opt for the latter, despite the supposedly high casualty rate, so the other three do the same, only to discover that Archie and Bill have gotten themselves safe jobs at the base. However, the war ends before any of them see combat. ........
