Development
In 1998, TriStar Pictures released their Hollywood reboot Godzilla. However, plans for a trilogy were cancelled due to the film's poor reception, and TriStar let their remake/sequel rights expire on May 20, 2003. In 2004, Toho Co., Ltd. released Godzilla: Final Wars to commemorate the franchise's 50th anniversary and to put the franchise on hiatus, due to low ticket sales and audience burnout, until demand increased for another film.
It is the second Godzilla film to be completely produced by a Hollywood studio. The American releases of Godzilla (Godzilla, King of the Monsters!), King Kong vs. Godzilla and The Return of Godzilla (Godzilla 1985) featured additional footage produced by independent Hollywood studios. The footage featured Western actors and merged it with the original Japanese footage in order to appeal to American audiences. Invasion of Astro-Monster was the first Godzilla film to be co-produced between a Japanese studio (Toho) and an American studio (UPA). The first Godzilla film to be completely produced by a Hollywood studio was the 1998 film.
In August 2004, Yoshimitsu Banno (director of Godzilla vs. Hedorah) announced that he had secured the rights from Toho to direct an IMAX 3D short film from his Advanced Audiovisual Productions (AAP) production company. The film was tentatively titled Godzilla 3D to the Max, and was to be a remake of the Godzilla vs. Hedorah story. In 2005, American Peter Anderson was added to the project as the cinematographer, visual effects supervisor, and co-producer by an independent producer Kenji Okuhira who represented Banno. In the same year, American producer Brian Rogers signed on to the project after the meeting with Banno arranged by Okuhira and Anderson.
In 2007, also through Anderson, Kerner Optical then came on board to develop the technology and to produce the 3D film and with Kerner's backing, in the fall of 2007, the team met with Toho in Tokyo where they re-negotiated their license to allow the release of a feature-length 3D theatrical production.
In 2008, Kerner was facing financial troubles that threatened to cancel the production. In 2009, Rogers, Anderson, and the then-proposed director Keith Melton met with Legendary Pictures to get their backing on a 3D theatrical film. In 2010, it was green-lit by Legendary to go to production. From the Godzilla 3D production team, Banno and Okuhira would remain on the project as executive producers and Rogers as a producer. In November 2013, Banno stated that he still planned to produce a sequel to Godzilla vs. Hedorah. However, Banno died on May 7, 2017.
In August 2009, rumors surfaced that Legendary was in talks with Toho to produce a new American Godzilla film to be released in 2012. On March 29, 2010, Legendary officially announced its acquisition of the Godzilla license and plans to produce a new film with Warner Bros. co-producing and co-financing. Legendary's Godzilla would be closer to the Toho version and avoid connections with the 1998 film. Producer and then-CEO of Legendary Thomas Tull elaborated on Legendary's plans: "Our plans are to produce the Godzilla that we, as fans, would want to see. We intend to do justice to those essential elements that have allowed this character to remain as pop culturally relevant for as long as it has." Film producers Dan Lin, Roy Lee, Doug Davison and Legendary's Thomas Tull and Jon Jashni were added to the project as producers to work with Rogers, Banno and Okuhira. Legendary financed 75% of the film's budget while Warner Bros. financed 25%. As a slate finance partner of Warner Bros., RatPac-Dune Entertainment had a minority stake ownership over the film, as well as other Warner Bros. titles.
At the 3D Summit conference held in September 2010 at Universal Studios, producer Brian Rogers confirmed a targeted release date for 2012, and that the reboot would be a live-action project featuring a fully CGI Godzilla battling two other monsters rather than simply the military as seen in Emmerich's 1998 film. Rogers also confirmed that the two Godzilla head designs online rumored to have been designed by Legendary and sent to Toho for approval were fake. Rogers also stressed his and Legendary's wish to revive Godzilla in the same fashion Legendary had revived Batman with Batman Begins (2005).
In October 2010, Latino Review reported that Legendary had merged the spec script for Pacific Rim with their Godzilla reboot and offered Guillermo del Toro to direct it. However, Del Toro clarified to Hitfix that the report was false, stating, "I am not involved in 'Godzilla' at all. I haven't read it or plan to read it. Nor have I been approached to direct it." Legendary would go on to produce Pacific Rim as its own film, with Del Toro directing, co-writing, and co-producing, and theatrically released it on July 12, 2013. In January 2011, Gareth Edwards was announced as the director for the film. In an interview publicizing the DVD release of Monsters, Edwards discussed the new film: "this will definitely have a very different feel than the 1998 film and our biggest concern is making sure we get it right for the fans because we know their concerns. It must be brilliant in every category because I'm a fan as well." Edwards further stated, "Without addressing anything specific, everyone knows how important it is to get it right."
The film remained in development into 2012, missing the planned release date. Edwards worked on his vision for the film at a stage at the Warner Bros. lot. The production team developed Godzilla models, artwork, and pre-visualizations of the action scenes of the movie. From the lot, Edward directed a short teaser video, shown to Legendary executives and later shown at San Diego Comic-Con in July 2012.
