Billy Gilbert and Shemp Howard teamed up to make so-so comedies, and Ghost Crazy is an amusing film, although it's a shame that the director, who went on to direct other horror comedies, didn't improve on his lighting techniques. Some scenes are filmed too brightly to see what's going on, while other scenes are filmed too darkly.
Anyway, Billy and Shemp, along with their friend Don are circus performers who get caught up doing good deeds because of Don's romantic interest in the leading lady. The film has moments that resemble scenes from "The Gorilla" and "The Blue Room". Abbott and Costello, and indeed, Laurel and Hardy might have done a better job, but this film is watchable.
