Kit Harington, the actor who played Jon Snow in “Game of Thrones,” is coming to the big screen. Harington, together with actress Gemma Chan, will be joining the cast of Marvel’s “The Eternals.” During the D23 Expo, Harington was revealed to have been cast as Dane Whitman, the hero known as the Black Knight.

The actor’s inclusion was confirmed by Marvel Studios President Kevin Feige, according to CNET. The Marvel exec made the announcement during Walt Disney Studios’ presentation at the D23 Expo. Also confirmed to join the cast was Gemma Chan of “Crazy Rich Asians,” who was cast to play another previously unknown Avengers team member, Sersi.

The announcements came after a series of Marvel news revealed at the D23 Expo. Disney unveiled its entire MCU slate for the Disney+ streaming channel, which will be launching Nov. 12. Harington and Chan will be joining Angelina Jolie, Kumail Nanjiani, Richard Madden, and Salma Hayek, who were previously confirmed to be onboard the project.

Harington, who most famously played the Stark and Targaryen bastard in “Game of Thrones,” is revealed to be not the only cast member to have been a part of the series. He is following the footsteps of fellow “GOT” star, Madden, who was Robb Stark in the series. Madden’s participation was announced earlier in the year, The Week reported.

Feige started the show by saying that they have “pulled back” the cosmic curtains on the MCU by bringing in “The Eternals.” The other cast members that were previously announced to be in the movie are Barry Keoghan, Brian Tyree Henry, Don Lee, Lauren Ridloff, and Lia McHugh.

“The Eternals” was created by Jack Kirby in 1976 featuring genetically modified humans who gained superpowers after their experimentation on by the alien race, the Celestials. They have a counterpart that went to the other end of the “superhero” spectrum. The Eternals’ evil counterparts that were similarly genetically modified are the Deviants.

The Black Knight is not an Eternal. It remains to be seen how he will be connected to the story, although in the comic books, he is constantly linked to the Eternal Sersi.
