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.
