In April 1977 Sandy Frank attended the MIP-TV conference in Cannes. It was here Frank first encountered the Japanese animation ‘’Gatchaman’’ from producer Tatsunoko Production run by the Yoshida brothers. Frank committed to release the series in the U.S. after he saw the success of Star Wars in May 1977. Battle of the Planets is the title of American adaptation of this series created by Frank. Frank authorized new footage and hired writers to add dialogue to fit the look of the animation, without reference to original scripts. Of the 105 original Gatchaman episodes, 85 were used in the Battle of the Planets adaptation produced by Sandy Frank Entertainment in 1978.
