- The world premiere of this film was on November 18, 1939 at the Sheridan Theater in Miami Beach, Florida, because the Max Fleischer Studio was in Miami, Florida. The New York City trade-showing premiere was two days later, and the national release date followed that by two days.
- To produce this feature film, the Fleischer studio had to nearly triple in size, from about 200 artists to nearly 700. Max Fleischer~ had a 32,000-square-foot plant built in Miami to accommodate the new personnel, as well as to take advantage of that city's tax exemptions on film studios.
