Theatrical agents Russ Matthews (Ralph Bellamy) and Al Tinker (Robert Armstrong) try to make a quick buck by promoting bibuolous vaudeville fortune-teller Dr. Fothergill (Raymond Walburn) as a genuine prophet. Amazingly, Fothergill's predictions come true, and soon his advice is being solicited by such shady types as gangster boss Cronin (Ed Pawley). This not only threatens the future existence of Matthews and Tinker, but also puts a crimp in Matthews' romance with girl reporter Carol Wilson (Betty Furness). The vaudeville and radio background of It Can't Last Forever affords several opportunities to inject specialty acts into the storyline. Among these is a personable trio of juvenile singers called the Dandridge Sisters, featuring 14-year-old Dorothy Dandridge in one of her first screen roles. ~ Hal Erickson, Rovi
