What does amuse me with Das Boot and other films is the various translations of the German. For example, in the DVD I have, when the news of the convoy comes through which eventually results in them running into that single destroyer (you know where I mean), the engineer flames off some fuel, and someone from up the front walks through and in one version says:
"What a way to waste fuel, eh?"
and in tonights version says:
"Having fun down here?"
Make up your minds!!!
