5 Celebrities You Forgot Guest Starred On Game Of Thrones

Here are five celebrities who made guest appearances on Game of Thrones:

1. Hannah Waddingham, known for her role as Septa Unella, played a villain in the series. She was best remembered for her chanting and ringing bell during Cersei Lannister's walk of atonement. Her performance was particularly challenging, as she described being strapped to a wooden table for ten hours during the scene where Cersei pours wine on her face.

2. Ed Sheeran, who appeared in the Season 7 premiere as a Lannister soldier named Eddie, was a favor to fellow musician Maisie Williams. His role was controversial because of his high-profile status, and he defended himself by explaining that he was "omnipresent" in pop culture at the time.

3. Sigur Rós, an Icelandic band, made a cameo in Season 4 during Joffrey's wedding. The band played at the wedding, but Joffrey dismissed their performance and threw gold at them. They later released a cover of "The Rains of Castamere" and appeared in other episodes, including Season 6's "The Door" and Season 8's "Hardhome."

4. Rob McElhenney, co-creator of It's Always Sunny in Philadelphia, had a cameo in Season 8's premiere as an Ironborn soldier who gets an arrow through his eye during a naval battle. He shared a photo of his injury on Instagram with the caption, "Don't blink."

5. Chris Stapleton, Will Champion from Coldplay, and Gary Lightbody from Snow Patrol also appeared in various episodes of Game of Thrones.
