The actor announced the news on May 26 after it was reported last week that he was being eyed for the role.
“Very excited to be joining the DC Universe!! Can’t wait to get started. #GreenLantern,” he captioned an Instagram post.
Irvine will join Finn Wittrock in the series, who has been cast in the lead role of Guy Gardner.
Scott was Earth’s first Green Lantern, who, true to the comics, is a gay man. He was created by Martin Nodell and made his comic book debut in 1940. A train engineer by trade, Scott derived his powers from a mystical green lantern crafted from a mysterious meteorite. He later joined the Justice Society of America, and in universe-hopping adventures would sometimes team with members of the Green Lantern Corps, including Hal Jordan.
Based on the DC Comics property, the show was first announced in 2019 and was ordered to series last year. The story spans decades and galaxies, beginning on Earth in 1941 with Scott, and then heading to 1984 with cocky alpha male Gardner and half-alien Bree Jarta. They’ll be joined by a multitude of other Lanterns — from comic book favorites to never-before-seen heroes.
Irvine most recently starred in the USA Network series “Treadstone.” He is primarily know for his feature work, having starred in films like “War Horse,” “The Railway Man,” “Mamma Mia! Here We Go Again” and “Billionaire Boys Club.” Irvine also played the lead role in Roland Emmerich’s 2015 film “Stonewall,” about the landmark riots in New York City in 1969 that launched the LGBTQ rights movement as we know it today.
Irvine is repped by UTA, Independent Talent Group, Schreck Rose and Relevant PR.
HBO Max has ordered 10 one-hour episodes of “Green Lantern.” The series is co-written and executive produced by Greg Berlanti, Seth Grahame-Smith and Marc Guggenheim, with Grahame-Smith serving as showrunner. Geoff Johns, Sarah Schechter, David Madden and David Katzenberg also executive produce, with Elizabeth Hunter and Sara Saedi co-executive producing. Berlanti Productions will produce in association with Warner Bros. Television.
