25 actors you forgot were on Game of Thrones

6. Rob McElhenney

Number of episodes: 1

Character name: Ironborn #1

We have another celebrity cameo. In fact, It’s Always Sunny in Philadelphia star Rob McElhenney made his appearance alongside Martin Starr, playing “Ironborn 1” to Starr’s “Ironborn 2.” McElhenney’s character, like Starr’s, was killed Theon Greyjoy and his men.

It was a very quick role, like a lot of other cameos. This was more about having fun than anything else. When it came to the bonus features and the goodbye special, McElhenney appeared still in all his makeup with the arrow-shot eye to share what happened. He clearly loved it all.

It’s not like McElhenney needed Game of Thrones for his career. Before this, we has (and still is) Mac in Always Sunny. He also plays Ian in Mythic Quest: Raven’s Banquet. He’s a writer and executive producer on both of these shows.
