Does the ‘House of the Dragon’ Cast Look Familiar? Here’s Where You’ve Seen Them Before

It’s been more than three years since Game of Thrones aired its final episode. And now, the show’s highly anticipated prequel, House of the Dragon, has finally arrived.

The brand-new series will air its first episode on Sunday, August 21. Since the show features a different cast than GoT, we compiled a list of actors and what else they’ve starred in. That way, you won’t have to pause the episode when you inevitably ask, “Where else have I seen him/her?”

Keep scrolling for details on the House of the Dragon cast.
