The episodes kept the original score by Bob Sakuma, though new music by American composer Hoyt Curtin was blended in to either fill in gaps where cuts were made or fill in silent moments. The voice cast consisted mainly of Hanna-Barbera regulars, such as Casey Kasem (Shaggy Rogers in Scooby-Doo) and Janet Waldo (Judy Jetson in The Jetsons). Animation of outer-space was added to give the impression that the Phoenix was flying through space, and that many of the episodes took place on Earth-like planets - another attempt to associate itself with Star Wars. The adaptation was heavily edited to remove violence and character fatalities, usually through cutting or dubbing explanatory voice-overs. Battle of the Planets differed significantly from its original source material. The acquisition was partly to capitalize on the success of Star Wars, which was released the prior year. Gatchaman was first adapted for English audiences in 1978, after the international license was acquired by Television producer Sandy Frank.
