This was the first in the "VS Series" of Godzilla films (sometimes called the "Heisei Series" due to the near-coincidence of its beginning with that of the Heisei era in Japan). It was Tanaka's intent to restore the darker themes and mood of the early films in the series. To this end The Return of Godzilla disregards all previous Godzilla films except 1954's Godzilla, to which it is a direct sequel. (It is later revealed that the Heisei continuity is an alternate reality to the Showa continuinity.) It features the lengthiest debate over the use of nuclear weapons in any Godzilla film (making reference to former Prime Minister Satō's Three Non-Nuclear Principles) and is only the third to depict innocent people being killed by the monster(s).
Godzilla arrives in Tokyo in the third act. He ends up damaging a missile control system on a Soviet freighter in Tokyo Bay and continues his rampage upon Japan. In another scene shortly afterwards, the last dying crewmember of the Soviet freighter docked in Tokyo Bay tries to abort the failsafe launch of a nuclear missile from a satellite in space in order to kill Godzilla. However, the crewmember is killed in the process. The SDF launches their newest weapon the "Super X" to combat Godzilla. During the initial confrontation, Godzilla is poisoned by cadmium shells fired from the Japanese flying fortress and is knocked out and dying. Meanwhile, the Japanese government finds out about the Soviet nuclear missile and asks the Americans to shoot it down. The Americans agree and are successful but the missile collision in the stratosphere causes a massive EMP, and then a radioactive lighting storm that revives Godzilla, allowing him to destroy the Super X and kill its crew and then continue his rampage. Scientists at Mt. Mihara manage to get their "lure" working, which calls out to Godzilla from across the Japan sea. Attracted by magnetic waves transmitted from their satellite dish on Mt. Mihara on Oshima Island, Godzilla falls for their trap. It is not until he is trapped in the mouth of the volcano that he awakens from his trance and realizes he has been lured into a trap. The SDF detonates a number of powerful explosions, which cause an artificial eruption. In the end he is trapped in Mt. Mihara, until 1989.
The Return of Godzilla was a reasonable success in Japan, with attendance figures at approximately 3,200,000 and the box office gross being approximately $11 million (the film's budget was $6.25 million). In terms of total attendance, it was the most popular Godzilla film since 1966's Godzilla vs. the Sea Monster.
Producer Tomoyuki Tanaka offered Ishiro Honda a chance to direct this film, but he strongly rejected the offer, because of what came of Godzilla in the 1970s, and his belief that Godzilla should have been permanently laid to rest after Eiji Tsuburaya's death. Also at around the same time, he was busy helping Akira Kurosawa on some of the films he was directing such as Kagemusha and Ran.
Veteran Akihiko Hirata, who appeared in several past Godzilla films—the best known of his roles of which is Professor Daisuke Serizawa from Godzilla—was slated to play Professor Hayashida, but he had died from throat cancer before production began. Yosuke Natsuki, another veteran, took the role instead. Stuntman Kenpachiro Satsuma (who previously played Hedorah and Gigan in Godzilla vs. Hedorah, Godzilla vs. Gigan, and Godzilla vs. Megalon) played Godzilla for the first time, as a replacement for another stuntman who backed out at the last minute.
Aside from being heavy, the suit was very dangerous (it was not only built from the outside in, but not made to fit him), and Satsuma lost a lot of weight after filming was done. This mildly mirrored what Haruo Nakajima went through when he played Godzilla in the original 1954 film. Subsequent Godzilla suits worn by Satsuma were much safer and more comfortable, as they were custom made to fit him (even though the suits still had some dangers of their own).
The lifelike animatronic Godzilla prop used in close-up shots is the 20-foot "Cybot Godzilla." It was heavily touted in the publicity department at the time, even though it was not used in the film as extensively as promoted. A full-size replica of Godzilla's foot was also built, but all of the scenes in which it is used were removed from the American version (the sole exception being a shot of the foot crushing a row of parked cars during the attack on the nuclear power plant).
The poster image was the same as for the Japanese version, but a green tinting was added to Godzilla's charcoal-gray skin.
New World's changes were not limited to these scenes. Much of the original version was deleted or altered. A partial list of the changes: 
The most controversial change was the scene where the Russian submarine officer Colonel Kashirin valiantly attempts to stop the launch of a nuclear weapon. New World edited the scene (and added a brief shot of Kashirin pressing the launch button) so that now Kashirin deliberately launches the nuclear weapon. This change is widely believed to be for propaganda purposes.
In addition, the theatrical release (and most home video versions) was accompanied by Marv Newland's short cartoon, Bambi Meets Godzilla.
The American version, with the added Raymond Burr footage, runs 87 minutes - 16 minutes shorter than the Japanese print.
Apart from the end credits (where he is listed as "Steven Martin"), Raymond Burr's character is never referred to by his full name, only as "Mr. Martin" or simply "Martin", for the entirety of the U.S. version. This was to avoid association with comedian Steve Martin.
The closing narration (spoken by Raymond Burr) is as follows:
The New World version of the film was almost universally lambasted by North American critics. Roger Ebert, who gave the film a mere one star in the Chicago Sun-Times, wrote:
"The filmmakers must have known that the original Godzilla (1956) had many loyal fans all over the world who treasured the absurd dialogue, the bad lip-synching, the unbelievable special effects, the phony profundity. So they have deliberately gone after the same inept feeling in Godzilla 1985. Examples: Dialogue: Is so consistently bad that the entire screenplay could be submitted as an example. My favorite moment occurs when the hero and heroine are clutching each other on a top floor of a skyscraper being torn apart by Godzilla and the professor leaps into the shot, says "What has happened here?" and leaps out again without waiting for an answer. Lip-synching: Especially in the opening shots, there seems to be a subtle effort to exaggerate the bad coordination between what we see and what we hear. All lip-synch is a little off, of course, but this movie seems to be going for condescending laughs from knowledgable filmgoers. Special effects: When Godzilla marches on Tokyo, the buildings are the usual fake miniature models, made out of paint and cardboard. The tipoff is when he rips a wall off a high-rise, and nothing falls out. That's because there is nothing inside."
Ebert kept a copy of the poster in his office for many years and it was clearly visible in the opening of his television program.
Vincent Canby of the New York Times (who had given a positive review to Godzilla vs. Megalon nine years earlier, a film that was critically hated) was similarly unimpressed:
"Though special-effects experts in Japan and around the world have vastly improved their craft in the last 30 years, you wouldn't know it from this film. Godzilla, who is supposed to be about 240 feet tall, still looks like a wind-up toy, one that moves like an arthritic toddler with a fondness for walking through teeny-tiny skyscrapers instead of mud puddles.Godzilla 1985 was shot in color but its sensibility is that of the black-and-white Godzilla films of the 1950s. What small story there is contains a chaste romance and lots of references to the lessons to be learned from "this strangely innocent but tragic creature." The point seems to be that Godzilla, being a "living nuclear bomb", something that cannot be destroyed, must rise up from time to time to remind us of the precariousness of our existence. One can learn the same lesson almost any day on almost any New York street corner."
One of the few positive reviews came from Joel Siegel of Good Morning America, who is quoted on New World's newspaper ads as saying, "Hysterical fun...the best Godzilla in thirty years!"
Given the scathing reviews and the American public's apathy to the genre, Godzilla 1985 did not perform well in the North American box office. Opening on August 23, 1985, in 235 North American theatres, the film grossed $509,502 USD ($2,168 per screen) in its opening weekend, on its way to a lacklustre $4,116,395 total gross. 
New World's budget breakdown for Godzilla 1985 is as follows: $500,000 to lease the film from Toho, $200,000 for filming the new scenes and other revisions, and $2,500,000 for prints and advertising, adding up to a grand total of approximately $3,200,000.
Taking this in consideration, Godzilla 1985, though not a hit, proved to be profitable for New World - a profit that would increase with home video and television revenue (the film debuted on television with a reasonable amount of fanfare on May 16, 1986).
Godzilla 1985 was the last Japanese-made Godzilla film to play in American theatres until Godzilla 2000 fifteen years later.
The DVD rights for The Return Of Godzilla are believed to currently belong to Anchor Bay/Starz Entertainment, who have no plans to release the film on DVD. The TV rights are held by Lakeshore Entertainment. It is hoped that the future release of "Godzilla 3D to the MAX" will pique interest in its release.
This film is able to be purchased on DVD but only in Japanese from Japan which they have made this 1991 VHS release into DVD format. It is recorded in Japanese dialogue but has English subtitles if needed. This also applies to Godzilla vs. Biollante.
In 2006, Universe Laser & Video Co. released a Region 3 DVD release of the film, titled The Return Of Godzilla. It was the original Japanese release, with Japanese Audio and selectable English/Chinese (Traditional, or Simplified). The DVD featured a main menu, scene selections, and a featured trailer of Godzilla Vs Biollante in Chinese.
