Die Gans von Sedan

This movie was made just before I was born. It's been aired on TV in France a few times only. As far as I can remember the plot, Hardy Krüger and Jean Richard are soldiers of the two opposite side that are forced to live together in a French farm held by Danny Karel. Hardy Krüger knows a little bit of French Jean Richard is fluent in German. Hardy has the crush for their hostess and asks Jean - once befriended - how to say "I love you" in French. Jean, kind of upset by Hardy's insistance or mockingly translates "I love you" into something in French that in fact means "I don't give a damn". Hardy goes trying his line with Danny and after having told her she was pretty concludes with "I don't give a damn of it". Later (or earlier), Jean and Hardy, totally drunk, praise the merits of their respective French and German made rifles. They take them apart demonstrating the quality of their craftmanship but are unable to reassemble them ... they'de mixed up the parts. I've loved this movie some much that 30 years ago I still have it in mind. I hope to see it released in DVD.
