The song Babalu was published in 1939 and the Broadway show was in 1940. Desi Arnez had a big name in the U.S. already and I don't think anyone else was up for the role. The movie was just a propaganda Latin American goodwill film one of many. RKO did not put any of there big stars because it was not a big film. The love stories in musicals was a normal type of story. The film is likable and I would watch it again. The stars don't seem to have the chemistry as love interest. It is interesting that all studios were making films that take place south of the American border but were filmed in there Hollywood studios except for a couple of examples.
