Although Tom August and Helen August were given credit for the screenplay when the film was initially released, according to official WGA records, Tom and Helen August were pseudonyms for writers Alfred Lewis Levitt and Helen Levitt. The WGA changed the screenplay credit to read: "Written by Alfred Lewis Levitt and Helen Levitt." The Monkey's Uncle was a sequel to Walt Disney's The Misadventures of Merlin Jones (see entry above).
