This isn't the only Casablanca knock-off ever made. Republic Pictures was known for its cowboy movies (Autry, Rogers, et al) but once and awhile ventured into better pictures, especially those of John Wayne. I'm not saying this was a good movie, just that it came from a source with little experiernce of making a good movie.
I've seen several movies with Vera Ralston in the cast. I think a mention should be made of her dancing in this one. After Sonja Henie introduced dancing into women's figure skaing, every other skater took dancing lessons. Ralston was perhaps one of them.
I don't think a double was used for Ralston's dancing. If you watch it carefully (I did 3 times), watch her turns. She turns like a skater, not a dancer. Dancers don't usually pull their forearms in to turn or tuck their forearms to the chest, as Ralston did in this dance.
