Alec Guinness' other heist-comedy ("The Ladykillers") might have a slight edge over this one, but funnily enough, I prefer the actual heist from this movie. Guinness is a mild-mannered bank supervisor who oversees the gold bullion shipments for the bank of England. When a frustrated artist (who makes lead paperweight replicas of the eiffel tower to sell to tourists in Paris) moves into his building, he gets an idea on how to smuggle stolen bullion out of the country. With the help of two criminal-type accomplices, the heist is planned out and executed to perfection. The police are quite perplexed and unsuspecting of Guinness, until one exceptionally clever member of scotland yard begins to suspect him. There are a few madcap chases in the movie which incorporate screwball comedy elements, but mostly the film's comedy relies on sublty rather than broad strokes. Guinness is fine, as usual, but the film itself isn't life-altering or mind-blowing in any way. Oh, it's perfectly serviceable, especially if you're looking for a mildly amusing crime-comedy, but I certainly wouldnt' call it a must-see.
