Jason Momoa was unforgettable as Khal Drogo.

Jack Gleeson took a break from acting for a while after exiting "Game of Thrones," though he returned to the stage for a play called "Bears in Space" in 2016.
We'll spare you a shot of Oberyn getting his head smashed in, but fans will never forget seeing Pedro Pascal's final moments as the Red Viper.
Pascal starred opposite Matt Damon in 2017's "The Great Wall." You can also catch him on Netflix in "Narcos."
One of the most heartbreaking deaths was when Ygritte — played by Rose Leslie — died in Jon Snow's arms.

In season six, Roose Bolton — played by Michael McElhatton — was one of the first characters to be killed off.
Michael McElhatton can be spotted among other "Game of Thrones" alumni in the upcoming Guy Ritchie movie "King Arthur: Legend of the Sword."
Ramsay Bolton also ruthlessly murdered Osha — played by Natalie Tena.
Now Tena has been cast in a pilot for a new CBS drama series with Jeremy Piven called "Wisdom of the Crowd."
Kristian Nairn nailed every "Hodor" he had to Hodor on "Game of Thrones."
His time on the show may be over, but Kristian Nairn has built a strong DJ career over the past few years. He still tours, and you can catch "Rave of Thrones" at a city near you.
Ian McShane had a brief stint on "Game of Thrones" as Brother Ray.
Now you can see McShane in Starz new fantasy series "American Gods," which is based on the Neil Gaiman book of the same name.

Davis went on to appear in the "Assassin's Creed" movie, and now she's playing a queen opposite Michelle Fairley in Starz's show "The White Princess."
Iwan Rheon expertly played the psychotic Ramsay Bolton, who was finally killed at the end of season six.
Iwan Rheon was cast as the leading role in a new Marvel series called "Inhumans," slated to premiere in November 2018 on ABC.
Margaery Tyrell met her end too soon in the season six finale, which meant no more Natalie Dormer for "Game of Thrones" fans.
Since season six ended, you can hear Dormer as the voice of Dr. Lexi T'Perro in the new "Mass Effect: Andromeda" game.
Margaery's brother, Loras, met the same fiery end as her. Actor Finn Jones had a pretty solid gig lined up though.
Now Jones is playing Danny Rand in Marvel's "Iron Fist" series on Netflix.
The High Sparrow — played by Jonathan Pryce — was another figure who was literally burned by Cersei in the season six finale.
Pryce is also starring in FX's new series "Taboo" (along with Oona Chaplin and Tom Hardy).
Roger Ashton-Griffiths played Mace Tyrell, father to Loras and Margaery and yet another victim of Cersei's wildfire plot.
Ashton-Griffiths is yet another "Game of Thrones" alumni you can now see in FX's new series "Taboo."
