So much has already been said about the sensational Joan Blondell who deservedly got top billing in this film. She was a multi-talented actress who could play any role given her better than anyone else. She was also a topnotch comedienne as she shows in this outing when she somewhat assumes the role played by Constance Bennett in the first two outings. Donald MacBride as the police sergeant in charge of investigating the murders plays the part of a dumb policeman (typical for Hollywood in those days) in such a lofty comic manner than his stupidity is actually believable and this time funny. Adding to the creepiness of this truly scary comedy is the performance of Rafaela Ottiano as the housekeeper. She would frighten the pants off Boris Karloff and Peter Lorre. The rest of the cast made in heaven is just as effective.
Special note should be given to the special effects which were nominated for an Oscar. The man behind them, Roy Seawright, had also been in charge of the special effects for the first two Topper's. I've read that he had a hand in doing the special effects for the 1933 horror classic "The Invisible Man," although he is not credited with that in his profile.
Roland Young is for many viewers the definitive Topper but the later TV Topper, Leo G. Carroll, did a fine job too. Plus the later TV series added a ghost St. Bernard named Neil who just happened to be an alcoholic. Except for this the three movie versions are superior. The made for TV "Topper Returns" actually deals with Cosmo Topper Jr. and though OK is nowhere near the caliber of this "Topper Returns."
