There is an old comedy movie I've seen. I believe it is pre-code, but certainly from the 1930's. The scene that's in my head is early in the movie in which an actress is in a bathtub, singing. What made the scene stick in my head is that it appears that helium or hydrogen is being bubbled into the tub, creating bubbles and foam which gently floats from the tub towards the celing.
I've tried doing searches but haven't had any luck. I'm hoping someone can help me find this film again.
Thanks all.
