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

It’s been more than four years since Game of Thrones aired its final episode. And now, the show’s highly anticipated prequel, House of the Dragon, has filled the Westeros void—and a second season is already on the way (even if we don't have an exact premiere date yet).

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 that actor?”
