Roy Fleming (
Don Knotts) is signed on to the space program at NASA by his father Buck (
Arthur O'Connell), a gung-ho former World War I vet who is trying to make something out of his son. Roy becomes a janitor who is afraid of heights and mistaken for an astronaut through a series of comedic mishaps. (
Jesse White) plays Roy's boss Donelli, with (
Leslie Nielsen) as space hero Major Gifford. Knotts uses his patented brand of nervousness to perfection in this lighthearted situation comedy. ~ Dan Pavlides, All Movie Guide
