I liked this movie, I have seen it at least 5 times so far. Let's be fair to the movie,it is not Gone With The Wind, it is a B movie, but a really cute one. Kay Kaiser is always Great.
This movie has a GREAT gimmick called the Sonovox. It is similar to the electronic voice box of today, but with much better fidelity. Two small very high powered speakers are held against the upper throat, and you just mouth the words, the speakers provide the voice. Peter Frampton used a variation of this for one of his songs.
There is a wonderful demonstration of the Sonovox at the end of the movie.
Also the big band numbers are great. The two main singers "Handsome" Harry Babbitt and "Gorgeous" Ginny Simms have very fine voices and sing very fine songs in the movie. Yes "The Bad Humor Man" is silly but "WHO CARES"?
The three "horror" stars are great too, Bela Lugosi steals the show, Peter Lorre smokes up a storm, and Boris Karloff is oddly restrained. If you like Big Band music and Old Movies, I think you will like this one.
