Another Wild Idea (1934)

Stars:

Charley Chase, Betty Mack, Frank Austin

Betty's father has an invention that looks like a fancy camera; it emits an ultra-lavender ray that temporarily rids the ray's target of inhibitions. To test it, Betty's father zaps Charley hoping his newly-aberrant behavior will cause Betty to end her affections for the milquetoast. Dad's plan backfires: the invention works perfectly, Charley gets a backbone, and Betty loves her new forceful man. However, Charley's courage and lack of a superego get him in trouble with the law. He goes on trial for assaulting a bullying police officer. Is Charley going up the river leaving Betty high and dry?
