Warning: spoilers for Game of Thrones season eight ahead.

A behind-the-scenes look at the Game of Thrones season eight set revealed two unexpected celebrity cameos in Sunday’s premiere. It’s Always Sunny in Philadelphia co-creator and star Rob “Mac” McElhenney and Silicon Valley’s Martin Starr, aka Gilfoyle, played two ill-fated Ironborn extras. Watch them recount their experience in the video above.

McElhenney and Starr played two of Euron Greyjoy’s men, both of whom meet swift and gruesome deaths at the hands of Theon Greyjoy as he fights to free sister Yara. The two appeared to enjoy the experience. McElhenney, whose eye is shot through with an arrow in the episode, posted “Don’t blink” in the Instagram post below.

The rest of the cast, however, were more preoccupied with the presence on set of George Lucas.

“When we found out that George Lucas wanted to visit, we thought maybe it was a practical joke,” said Game of Thrones co-creator and showrunner David Benioff. “And then we were really excited and also nervous because it’s George Lucas.” The Star Wars creator made a surprise visit to the set during the filming of the “Winterfell” episode’s homecoming parade.
