In the early 1940s Walt Disney was developing a feature film based on Roald Dahl's book "Gremlin Lore", and asked the other studios to refrain from producing gremlin films. While most of the studios complied, Warner Bros. already had two cartoons too far into production - this cartoon and Russian Rhapsody (1944). As a compromise, Leon Schlesinger re-titled the cartoons to remove any reference to gremlins. The original title was "Bugs Bunny and the Gremlin".
