In trying to educate our US colleagues out here in sandy places, I showed the The Dambusters (1955 version) just yesterday over a pizza and nea-beer! Despite much gnashing of teeth when forementioned hound made his first appearance the concensus was 'brilliant', 'awesome' and 'best flight movie I've seen'.
Not sure if these foreign votes count against the survey or not, but the Dambusters gets my vote every time!!!
