The TV series Game of Thrones has employeed thousands of extras over the past 8.1 seasons ... They may not make the millions of dollars the stars of the show make - but they certainly put in the effort.  Many of them have named their characters and created back stories to their character's life. 

 

There's also been a lot of celebrity cameos on the show - notably Ed Sheeran, Sigur Ros, Of Monsters and Men, Steve Love, and Mastadon to name a few .... 

 

AND - if you had a keen eye - you caught two cameos on episode one of season 8 -  It’s Always Sunny in Philadelphia’s Rob McElhenney and Silicon Valley’s Martin Starr  - YEP - Mac and Gilfoyle - were on the show ... briefly ...  Missed it - check it out below:
