Just a few days ago, we brought you the news when Morgan Freeman (The Dark Knight Rises) joined the cast of Universal Pictures big-screen adaptation of writer-director Joseph Kosinski‘s (Tron: Legacy) graphic novel Oblivion, in a so-far-unrevealed “critical” role opposite Tom Cruise, Olga Kurylenko and Andrea Riseboroug.

Now, Deadline reports that Nikolaj Coster-Waldau (Game of Thrones) has signed on to co-star in the film as Sykes, a battle-hardened, physically imposing, intelligent and extremely athletic military technology and weapons expert, in the film that sees Tom Cruise as a soldier stationed on Earth, the surface of which has been destroyed by aliens. When he discovers a mysterious woman in a crash-landed pod, it sets off a chain of events that cause him to question everything he knows.

Oblivion is slated to hit theaters on April 26, 2013.
