This is such an overlooked gem it is really unbelievable that It is not to be seen on TV for many years, at least not in German speaking countries. I remember I saw this film dubbed in German when I was a child, must have been in the 70s, but since than... nothing. I bought a DVD from Spain which also has the original English version on it. Danny Kaye shines in what he was best, playing doubles, something no other screen actor did so often and so well. Here he does the incredible, he splits into a comic and a completley serious character, forshadowing his serious roles to come. I am a great fan of Danny Kaye but I fairly admit not all his films are as good as this one!
