Return to the Planet of the Apes concepts would be Tim Burton's reimagining in 2001. Along with the second film "Beneath the Planet of the Apes", this is one of only two original "Planet of the Apes" productions in which Roddy McDowall was not involved. In 1975, after the failure of the live-action series, NBC and 20th Century Fox agreed to adapt "Planet of the Apes" for an animated series. The network contracted DePatie-Freleng Enterprises to produce a half-hour Saturday-morning cartoon titled "Return to the Planet of the Apes". Doug Wildey, co-creator of "Jonny Quest", took on most creative control as associate producer, storyboard director, and supervising
Planet of the Apes installment. Jacobs died on June 27, 1973, bringing an end to the APJAC Productions era of the "Planet of the Apes" franchise. Former Fox executive Stan Hough took over as producer for the television project, titled "Planet of the Apes". CBS picked up the series for its 1974 autumn lineup. Ron Harper and James Naughton played Alan Virdon and Peter Burke, two 20th-century American astronauts who pass through a time warp to a future where apes subjugate humans (unlike the original film, the humans can speak). Roddy McDowall returned to the franchise as Galen, a chimpanzee who joins the astronauts.
