Actor Henry Winkler first became aware of the script for this movie when he ran into actor Dustin Hoffman in a doorway of a New York building. Hoffman talked for about three minutes about some screenplays he owned the rights to and about a year later Winkler received a copy of this film's script.
Actor Henry Winkler is seen sporting peroxided blonde hair in this movie. The name of the blonde-haired ballet-costume wearing wrestling character with a harem of girls that Andy Schmidt (Henry Winkler) creates was called "The Lover" or "The Great Lover', and he is 'The One And Only' of the film's title. The character and film's story was based on glamor wrestler Gorgeous George (real name George Raymond Wagner) and his career. This picture was made and released about fifteen years after Gorgeous George had passed away. Winkler once commented that George had blond curls and sprayed himself in the ring with perfume, "If that doesn't shatter my Fonz image, nothing will!".
This movie was made and released about 27 years after the year in which it is set, 1951. This was the year that the film's wrestler inspiration, Gorgeous George, was at the peak of his fame, being parodied as "Ravishing Ronald" in a Warner Bros. "Merrie Melodies" animated short 'Bunny Hugged' that year. In 1952, George was spoofed by the Bowery Boys in No Holds Barred (1952).
