In addition to appearing in The Witcher season two on Netflix, actor Graham McTavish has joined the cast for the Game of Thrones prequel series, House of the Dragon--or at least we're pretty sure he has. Speaking to Stylist about the rumors that he's in the show, McTavish basically confirmed it without saying Game of Thrones.

　　"I'm enjoying that, yes," he said. "I'm really having a lot of fun. We've just started. It's a very big project, so we're getting to know each other. They're lovely people. It's great, but I can't tell you too much. I can't tell you really anything about the story! But it involves a lot dragons."

　　McTavish was spotted on the set of House of the Dragon, and people believe he will play Harrold Westerling on the show.

　　McTavish stars on Outlander alongside Sam Heughan. They conducted the Stylist interview together, and Heughan asked, "Am I in [House of the Dragon]?" McTavish said with a laugh, "So far, no. And I have been waiting… I have to say 'Where is Sam?' because it's always in my contract now."

　　Heughan actually auditioned for Game of Thrones seven times, but it never worked out. "I auditioned for Renly, Loras, some of the members of the Night's Watch. And I'd always get so close! I'd be like, 'Guys, just give me a sword!'" he told Vulture.

　　McTavish also played the hobbit Dwalin in Peter Jackson's The Hobbit, and, as mentioned, he will be seen in season two of The Witcher on Netflix. Outside of film and TV, McTavish is known for his roles in the video game franchises Uncharted and Call of Duty.

　　House of the Dragon is based on George R.R. Martin's book Fire & Blood. The story follows House Targaryen and is set 300 years before the Game of Thrones story.

　　The first House of the Dragon images were recently released, showing off Matt Smith (Doctor Who) as Prince Daemon Targaryen and Emma D'Arcy (Truth Seekers) as Princess Rhaenyra Targaryen. House of the Dragon is scheduled for release in 2022.
