13 hidden cameos you probably missed on 'Game of Thrones'

• "Game of Thrones" has been full of cameos throughout its eight seasons
• The final season premiere featured brief appearances from Rob McElhenney and Martin Short
• Ed Sheeran, members of Coldplay and Snow Patrol, and showrunners David Benioff and D.B. Weiss are among the many celebrity appearances

In its almost eight seasons, "Game of Thrones" has featured many prominent figures in brief cameos, sometimes as short as one or two quick shots. The massive popularity of the show has attracted celebrities, many of which are huge "Game of Thrones" fans themselves.

We rounded up some of the most notable celebrity cameos. It's worth noting that for our purposes, musicians who played supporting roles like Wilko Johnson as Ser Ilyn Payne and Joel Fry as Hizdahr zo Loraq aren't cameos, nor is the prosthetic head of former President George W. Bush on a spike in season one.

Rob McElhenney and Martin Starr both made bloody cameos on the season eight premiere.

In the season eight premiere, two soldiers were brutally shot through the eye as Theon boarded the Greyjoy ship to save Yara. That was "It's Always Sunny in Philadelphia" actor and creator Rob McElhenney and Martin Starr, from "Freaks and Geeks" and HBO's "Silicon Valley."

McElhenney is a huge fan of the show and is close with the showrunners. Weiss and Benioff wrote an "Always Sunny" episode in 2013.

Of Monsters and Men had a musical cameo — twice.

The folk-pop band has made two appearances as a traveling band in the background of "Game of Thrones" scenes.

The first cameo was during the infamous Purple Wedding in the second episode of season four. The band returns in season six, performing background for the production of "The Bloody Hand" we see in Braavos in episode six, the one that mocks some fan-favorite characters in an over-the-top production.

Ed Sheeran had a polarizing cameo.

The Ed Sheeran cameo in the seventh season premiere was pretty polarizing. By far the biggest artist to land a "Thrones" cameo, Sheeran played a Lannister soldier who doubled as a bard. You can hear him singing "Hands of Gold," an original composition written for the show, before sitting down for a friendly meal and drink with his troupe and Arya.

For those who weren't a fan of that scene, you can rejoice that the show may have nodded to Sheeran's character meeting a grisly fate.
