Battle of the Planets

[3] The adaptation was generally faithful to the plot and character development of the original Gatchaman series, but significant additions and reductions were made in order to increase appeal to the North American television market of the late 1970s, as well as avoid controversy from parents; these included the removal of elements of graphic violence and profanity.

[6] An oft-delayed CGI film based on the franchise, Gatchaman, last slated for a 2011 release from Warner Bros., was officially canceled in June 2011.

New footage was authorized and Frank hired writers to add dialogue to fit the look of the animation, without reference to original scripts.

Keyop's "Space Bubble", an all-terrain, tank-like vehicle capable of VTOL as well as being a submersible craft, was held in the right storage capsule of the Phoenix.

The G-Force team themselves would use a combination of martial arts skills, ninja-like weapons, and their "cerebonic" powers to dispatch hordes of enemy soldiers and overcome other obstacles.

Their bird-like costumes include wing-like capes that could fan out and function nearly identically to parachutes and/or wingsuits, enabling the G-Force members to drift or glide down to safety from heights that would otherwise prove fatal.

Other weapons include feathers with a sharpened steel quill that could be used as deadly throwing darts and mini-grenades shaped like ball bearings with spike studs.

Setting, violence, objectionable language, and certain character fatalities were altered or eliminated by cutting scenes, dubbing, and explanatory voice-overs (for instance, claiming that the city had been evacuated before a battle scene that would show the incidental destruction of buildings and houses, as well as explaining away the destruction of the Earth armies and air forces as being robot tanks and fighter planes).

[12][13] One of the most notable changes in the BotP adaptation involves the character Keyop (Jinpei in Gatchaman), who picked up a bizarre verbal tic of stuttering, chirping, and burbling every time he started to speak.

There was a longstanding fan rumor that this was done because the original character spoke using much profanity and that Keyop's excess mouth motion would cover up deleting the words.

[14] The main villain, known as Zoltar in BotP, had an unusual background due to the gender changing mutant nature of the original Berg Katse character.

)[14] To compensate for the other differences, a robot named 7-Zark-7—who watched over G-Force from their base, Center Neptune—performed explanatory voiceovers and light comic relief, which not only padded the time lost from editing but also filled in the gaps in the storyline.

In 1986, Gatchaman was re-worked in the US as G-Force: Guardians of Space by Turner, with a good deal of the original content edited out of Battle of the Planets put back into the show.

[15] Among the Top Cow comic books was Battle of the Planets: Princess, written by David Wohl with art by Wilson Tortosa, released in 2002.

[21][22][23] Aimed at the 6-11 male demographic, the project was conceived when d-rights expressed interest in Nelvana rebooting the franchise following the success of the second generation of Beyblade.

[24] No new information on the project has surfaced since 2016 and it appears to be scrapped as Nelvana's parent company Corus Entertainment removed the press release from their official website.

It was announced at the 2019 San Diego Comic-Con that Joe and Anthony Russo are producing a live-action Battle of the Planets film through their production company, AGBO, with the possibility of directing.
