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?”

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