The Fuller Brush Man is a 1948 comedy film starring Red Skelton as a doortodoor salesman for the Fuller Brush Company who becomes a murder suspect.
The project had been in development for four years. Producer Simon got permission from the Fuller Brush company and wrote the story with Skelton in mind but was unable to secure studio interest until the success of Miracle on 34th Street 1947 showed the benefits of commercial tieins for feature films. He set the project up at Columbia conditional upon MGM agreeing to loan him out. Producer Edward Small was owed a favour by MGM as he agreed not to make a film called DArtagnan to clash with their production of The Three Musketeers 1948. Small and Simon then purchased a story in the Saturday Evening Post by Roy Huggins. Fuller Brush gave their final approval provided it was clear in the final movie that the character Skelton played was an independent dealer and not an employee of the Fuller Brush company.
