Fanfaren der Liebe

Billy Wilder may have said that he only used the premise of this film and one scene in SOME LIKE IT HOT, but aside from the absence of gangsters in the original and women who seem to catch on a lot quicker to what's going on, I didn't see many dissimilarities.

Both films are a lot of fun - although back to back viewings will be problematic for most unless they're someplace that does excellent scheduling of foreign films. I doubt you'll find this one in any recorded form easily.
