Videos by ComicBook.comAccording to Deadline, Severance actor Ólafur Darri Ólafsson has been cast to play Thor in God of War. Thor made a brief appearance in a secret ending cutscene in the 2018 God of War game before having an expanded role as a secondary antagonist in Ragnarok. What Thor’s Role In God of War Season 1 Could BeThor only makes a cameo in God of War, but there’s a very organic way to give him a meaningful role in the show’s first season. By casting Thor now and making him part of God of War Season 1, the idea is to likely flesh out the dynamic between Thor and his offspring. Making deviations from the source material, especially something as beloved and acclaimed as God of War, is always risky.
