An obscure one, but don't miss it if you spot it in the video store or on cable: The Dam Busters. I also never get tired of Von Ryan's Express. It's cornball, but you've got to love the great performances--and those trains. Another I like is The Devil's Brigade. Hoods from the US team up with teddibly professional Canucks. And speaking of Canucks, how about 49th Parallel? Made in '41, it concerns a German U-Boat crew stranded in Newfoundland when Canada was at war but the US wasn't. Propaganda, sure, but intelligent filmmaking and a great story.
