The remasters begin with a 4K, 16-bit scan of the original 35mm successive exposure negative; special proprietary software is used to merge the successive exposure Technicolor negatives into a single RGB color image. The resulting shorts have been restored to the animators’ intended production quality.
The voice actors include Clayton “Bud” Collyer and Joan Alexander, who reprise their The Adventures of Superman radio show roles as Superman/Clark Kent and Lois Lane.
Extras include three featurettes. Superman: Speeding Toward Tomorrow explores the visual storytelling; First Flight: The Fleischer Superman Series brings together contemporary animators, comic book and animation historians, and Fleischer artist to discuss the shorts; and The Man, the Myth, Superman is a study of Superman-esque characters throughout history.
The Blu-ray will retail for $33.99.
