I have vaugue recollections from my childhood of watching a film with trucks loaded with Nitroglycerin being driven other mountain roads to a remote village.
I never knew the name of the film, and my parents, who presumably watched it as well have no idea.
Recently I came across Wages of Fear, but having watched it I know it is not the film I saw as a child, although the premise is very similar & it would have been about the same era.
Any guesses what the film I saw may have been?
