A movie in which a young girl is thrown onto the street by her guardians for the unthinkable crime of drinking ginger ale with a boy in a roadhouse is only ever going to have the most tenuous links to reality, and Mister Antonio subsequently has little to hold an audience's interest. Leo Carrillo comes over all Chico Marx as the title character in this slight tale, but he doesn't quite have the strength of personality to carry the movie - and comes across as downright creepy when attempting to persuade innocent young Virginia Valli to spend a night under the stars with him.
