As Young as You Feel (1951)

After his 65th birthday, Acme Printing plant worker John R. Hodges (Monty Woolley) becomes a victim of his employer's mandatory retirement policy. In a scheme to get his job back and the policy repealed, Hodges impersonates parent-company owner Harold P. Cleveland and arranges an impromptu visit to the plant that he hopes will leave the executives' heads spinning. But when his granddaughter's boyfriend, Joe Elliott, discovers his plot, it could ruin everything.
