Alexander Skarsgård as Nathan Lind
Alexander Skarsgård plays Nathan Lind, the Hollow Earth theorist whom Walter Simmons recruits and who persuades Monarch to move Kong. Deadline reported in October 2018 that he would star in Godzilla vs. Kong. Early Variety coverage described his part as the leader of a military unit, which differs from the role he plays in the finished film.
Rebecca Hall plays Ilene Andrews, a Monarch linguist who studies Kong and is raising Jia. Her casting was reported in late October 2018, in the same wave as Eiza González and before her character had been named. During production, Hall learned American Sign Language so she could communicate with Kaylee Hottle, according to NME.
Kaylee Hottle as Jia
Kaylee Hottle plays Jia, the young deaf orphan who has a close bond with Kong and uses sign language. Jia was her feature film debut, after she appeared, at age nine, in a 2017 commercial for the video relay service Convo. She returned as Jia in Godzilla x Kong: The New Empire (2024), directed by Adam Wingard, and died in July 2026, aged 18.
Brian Tyree Henry plays Bernie Hayes, an Apex Cybernetics engineer whose conspiracy podcast is followed by Madison Russell. Deadline reported in October 2018 that he had joined Godzilla vs. Kong, when he was fresh from Emmy nominations for Atlanta and This Is Us. Variety described the part as a significant role before the character name was public.
Millie Bobby Brown plays Madison Russell, who starts investigating Apex with her friends. Variety reported in October 2018 that she was reprising the role from Godzilla: King of the Monsters, which had not yet been released, so she was attached to Godzilla vs. Kong before audiences had seen her first Monsterverse film.
Julian Dennison plays Josh Valentine, one of the friends who joins Madison Russell as she looks into Apex. The Hollywood Reporter confirmed his casting in June 2018, which made the Deadpool 2 actor one of the earliest additions reported in the run of announcements that filled out the Godzilla vs. Kong cast that year.
Demián Bichir plays Walter Simmons, the chief executive of Apex Cybernetics, who recruits Nathan Lind after Godzilla attacks an Apex facility. The Hollywood Reporter reported in October 2018 that Bichir was in talks to join Millie Bobby Brown, Julian Dennison and Brian Tyree Henry in the cast, with Adam Wingard attached to direct.
Eiza González as Maia Simmons
Eiza González plays Maia Simmons, the daughter of Walter Simmons, who sends her along on the Kong expedition to represent Apex. Her casting was reported in late October 2018, around the same time Rebecca Hall was added, and neither actress had a named character when the news was announced.
Shun Oguri as Ren Serizawa
Shun Oguri plays Ren Serizawa, a senior Apex Cybernetics figure who works alongside Walter Simmons. Deadline reported in November 2018 that the role would be his Hollywood debut, introducing him as a Japanese star known for Crows Zero and its sequel as well as for Gintama.
Kyle Chandler plays Mark Russell, Madison's father, who now works with Monarch. He is one of two actors carried over from Godzilla: King of the Monsters, alongside Millie Bobby Brown, who returns as his daughter, Madison Russell. TMDB bills him tenth in the Godzilla vs. Kong cast.
Lance Reddick plays Guillermin, credited eleventh in the TMDB billing. Deadline reported his casting in November 2018, introducing him as the Bosch actor and noting that the film was then set for May 22, 2020. That date later changed several times, including a move to November 20, 2020, before the film opened in US theaters on March 31, 2021.
Hakeem Kae-Kazim plays Admiral Wilcox, credited twelfth in the TMDB billing for Godzilla vs. Kong. His character is one of two admirals in the credits, the other being played by Curtis Bush, who is credited simply as Admiral. After Kae-Kazim, the cast list continues with Ronny Chieng as Jay Wayne and a long run of guards, pilots and technicians.
