Much of the enjoyment inherent in Money Madness can be derived from watching Hugh Beaumont, nine years before his "Ward Cleaver" stint on TV's Leave It to Beaver, playing a low-down, dirty-rat heavy. Armored-car driver Steve Clark (Beaumont) gets tired of hauling around other people's money and begins drawing up plans to accumulate his own loot. Using inside information, Clark manages to pilfer 200 grand without arousing the suspicions of the authorities. He then weds heiress Julie (Frances Rafferty), for the express purpose of murdering both her and her wealthy aunt Cora (Cecil Weston). Only attorney Donald (Harlan Warde) figures out that the smooth-talking Clark is up to no good, but by then it's too late. Hugh Beaumont's cold-blooded performance in the film's final scenes is enough to make one fear for the future safety of Barbara Billingsley, Tony Dow and Jerry Mathers.
