Well, it's a period comedy with Bob Hope. If you like Hope, you will probably like this movie. Vincent Price, the "real" Cassanova was not even credited with his appearance in the film. As a person who is indifferent to Hope, I found this film to be generally annoying. It's a comedy and I maybe chuckled twice. I found Hope's performance to be completely consistent but ultimately tiring. It's like they thought up a 10 minute TV sketch and decided to make a full-length movie on it.
If you're interested in 1950's comedy in a similar vein you would do much better by viewing The Three Musketeers with Gene Kelly and Vincent Price. It's funny, and has much better action and stunt work. For a straight 50's comedy, take a look at Champagne For Caesar starring Ronald Colman and Vincent Price. Both are miles ahead of this picture.
