Hong Kong based animation studio, Imagi has aquired the rights from Tatsunko Production to produce a CG animated film based on the cult classic 70's anime, Gatchaman (Science Ninja Team Gatchaman). The studio is best known for producing the short-lived CG animated TV series, Father of the Pride for Dreamworks and its currently co-producing the Highlander anime (Highlander - Search for Vengeance) with Madhouse as well as producing the CG animated film, Teenage Mutant Ninja Turtle, schedule for theatical release in 2007.

To compensate for the other differences, an R2-D2-type robot named 7-Zark-7 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. Notionally, 7-Zark-7 ran the undersea monitoring station Center Neptune, from where he received information regarding incoming threats to Earth and relayed that information to G-Force. Zark and other added characters, such as 1-Rover-1, Zark's robotic dog (who could hover from one side of the control room to the other by spinning his tail like a propeller) and Susan (the early-warning computer whose sultry feminine voice often sent Zark into paroxysms) added to the cartoon's youth appeal.
