As per The Hollywood Reporter, while HBO is not commenting or confirming the casting, the actor was reportedly spotted in costume on the sets and recently said in a new interview with the UK fashion magazine Stylist that he is appearing in the upcoming show.

"I'm enjoying that, yes," McTavish said when asked about the series in an interview promoting his new documentary 'Men in Kilts'. He added, "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 of dragons."
