For me this one lives in the shadow of the 1985 reworking that starred Helen Mirren called 'Dead Woman's Shoes'. The original is a fair fantasy about a homeless man who takes on the personae of a dead mobster. Warren Stevens is more convincing when acting as the mobster's personality whose shoes are now literally filled by the homeless guy. The first transformation is gradual, but after meeting the dead man's girlfriend ,Wilma (Joan Marshall), the shoes cause instant changing when taken off and put back on. The fact that he doesn't look like the dead man puts him in a strong position to go out for revenge on his killer.
Average TZ, generally well carried by Stevens.
Joan Marshall played Herman's wife in the pilot episode of 'The Munsters'.
