The film opened at #6 at the Japanese box office and was panned by both US and Japanese film critics for its dull storyline, mediocre CGI effects and overuse of action film cliches. However, the critics praised the film's costumes and fight choreography.
In the original series, George Asakura went under the false name of "Joe Asakura" to protect himself from Galactor. In contrast, the film explicitly refers to him as "George Asakura" although the characters pronounce it as "Joe".
Jun and Jinpei's last name is revealed to be Ohtsuki, the film might be implying that they are biological siblings in this incarnation. In the anime, their last names were never revealed and Jinpei was Jun's adopted brother.
The Gatchaman costumes were one of the biggest production costs for the film, with the director wanting a "Hollywood level" quality to them. They took one year to design and construct and cost $40,000 US each for the five suits, resulting in a grand total of $200,000 (¥200,000,000 JPN) in production costs.
A nod to Jun being an orphan in the original series is made when Ken Washio mentions her parents being deceased. In this film, however, she makes a claim that they are actually being held captive; aside from a later flashback, that is the only time they were mentioned.
