Maybe this movie works better in Italian. The other reviews didn't seem to see this movie the same way I did, but I watched it with the Italian soundtrack. The Italian title is, Due Mogli Sono Troppe, Two Wives Are Too Much.
I agree that the male lead was less than inspiring, but he executed the film with talent, in spite of his appearance.
Sally Ann Howes came across sweeter and prettier than in the other two movies I know her for, Chitty Chitty Bang Bang and Dead of Night, although both of those movies are better constructed and are better productions than this one.
There were a number of scenes that had me laughing, if not quite rolling in the aisles.
All of the other characters were very sympathetic and carried the movie along well, particularly the secondary love interests, who I think were better looking than the leads. The townspeople really welcomed the audience into the town and into the movie.
This film is not deep or moving, but it does what it intended. It gets the audience into a fun silly situation and back out again. And while other movies like this can be frustrating, this one keeps the frustrating situations to a minimum.
