Guillermo del Toro revealed the latest scoop on "Pacific Rim 2" while at the Television Critics Association panel.

The sequel for del Toro's 2013 science fiction monster-action film was announced last month. According to Birth.Movies.Death, "Pacific Rim 2" will start production in Toronto's Pinewood Studios, and will have "Maelstrom" as its working title. He also revealed that the follow-up will kick off a few years after the original film's event and will center on the Kaiju, Global News reported.

"Pacific Rim 2" will feature Charlie Day and Burn Gorman as the main characters. When asked whether Charlie Hunnam's character, Raleigh Becket, will be at the background in the sequel, the 50-year-old filmmaker assured that the actor will still have a major participation, SlashFilm wrote.

He also dropped a big revelation about the cast lineup. "I think that everybody or most everybody that survived is back. The rest we killed. We killed half the cast," del Toro shared, as reported by the news outlet.

The Mexican director will once again pen the screenplay alongside Travis Beacham and Zak Penn of "X-Men: The Last Stand." "Pacific Rim 2" is expected to debut in theaters on August 4, 2017, Global News noted.

Guillermo del Toro Talks Other Projects

During the TCA press tour, del Toro also discussed his other projects, Disney's supernatural family movie "Haunted Mansion" and "Hellboy 3."

"Haunted Mansion," which del Toro is set to direct and produce, will star Ryan Gosling and was first announced at Comic-Con in July 2010, Variety wrote. Del Toro said that his version will not be comedic, as opposed to Eddie Murphy's 2003 film adaptation of the same name. However, it looks like the project is stuck in development.

"All you can do is develop the screenplays, send them in, get a reaction, get the budget, agree or disagree on budget and so forth," the filmmaker said of the movie, as quoted by SlashFilm. "Every project goes through the same thing. People say why do you have five [movies in development]? I have five because one happens . . . I have to have these projects alive to hope and pray that one of them happen."

"Hellboy 3," the third installment from the franchise starring Ron Perlman, also has the same fate as "Haunted Mansion." According to del Toro, the first and second "Hellboy" films made a lot of money thanks to home video (Blu-Ray and DVD), but "that market is done now," SlashFilm added. "Hellboy 3" is slated to be a bigger movie than its predecessors.
