There is a scene where the two American characters are at their hosts house in London when the home owner suddenly returns earlier than expected. Kline pulls a gun and hides behind a wall, prepared to shoot the "burglar". That scene was meant to be a joke, according to John Cleese the British audience heartily laughed at it but the American test audience remained stonefaced as this seemed normal behavior to them. They also cut most of the other scenes of his character playfully toying around with his gun. They originally shot several scenes of him shooting at cat's tails for sport but cut those out since neither of the test audiences liked that. They kept the scene where he is so angry to find the safe empty and the loot from the bank robbery missing that he shoots at the safe.
