But, he went on to win a Golden Globe for his role in the hit Netflix series Bodyguard, and has appeared in major films, including the Elton John biopic Rocketman, the acclaimed World War I drama 1917 and the MCU ensemble flick The Eternals.
And regarding any off-screen stuff, "I just keep my personal life personal," he told the New York Times in 2019. "I've never talked about my relationships."
Alfie Allen
Alfie Allen's family isn't as complicated as Theon Greyjoy's, but they're pretty famous: mom's a producer, dad's an actor and sister is Lily Allen. (Which means brother-in-law is David Harbour.)
But after he landed his breakout role at 2022, Allen had to ban his older sibling from talking about GOT in public.
"I am not even allowed to mention the letters of what the show starts with," Lily said during a 2014 interview with Australian radio station Nova 969. "Alfie put me under strict orders."

While he's starred in series like Harlots and White House Farm and appeared on Broadway in Hangmen, Allen also turned in a chilling performance as Oklahoma City bomber Timothy McVeigh in the indie thriller McVeigh, which premiered at the 2024 Tribeca Film Festival.
Allen welcomed a daughter with partner Allie Teilz in October.
Jason Momoa
Jason Momoa stole the show as Dothraki warlord Khal Drogo, a man of very few words, and has been working pretty constantly since his one-and-done season on GOT.
He joined the DC Universe as Aquaman, appearing in a handful of movies, including his 2018 standalone blockbuster, which grossed more than $1 billion worldwide, and its pandemic-delayed 2023 sequel, Aquaman and the Lost Kingdom.

Momoa married longtime partner Lisa Bonet, with whom he shares daughter Lola Iolani (born in July 2007) and son Nakoa-Wolf (December 2008), in 2017, but the pair announced in 2022 that they were splitting up after 17 years together. Bonet filed for divorce in 2024.
Momoa confirmed in May 2024 via date night PDA that he's been seeing Adria Arjona.
