You remember the moment. Jaime Lannister, resplendent in gold armor, shoves a ten-year-old boy out of a high window with a casual, "The things I do for love." In that single scene, the world met the kingslayer game of thrones actor, and we all collectively decided we hated his guts.
Except, we didn't. Not for long.
The man behind the golden hand, Nikolaj Coster-Waldau, pulled off one of the most complex "heel-turns" in television history. But honestly, looking back at 2026, it’s wild to realize how close we came to a completely different Jaime. Coster-Waldau wasn't exactly a household name in the States back in 2011, even though he’d been grinding in the industry since the early 90s.
The Danish Secret Behind the Kingslayer
Most fans don't realize that before he was a Lannister, Nikolaj was already a massive deal in Denmark. He had his big breakout in a 1994 horror flick called Nightwatch (Nattevagten).
He was young, he was intense, and he had this raw energy that caught the eye of Hollywood heavyweights like Ridley Scott. That’s how he ended up in Black Hawk Down (2001). But here’s the kicker: despite being in massive movies, he kept flying under the radar.
He once joked in an interview that he basically got the Black Hawk Down role by filming a self-tape in a cramped attic in Copenhagen and shipping it off, hoping for the best.

It worked.
But it took another decade and a failed Fox pilot called New Amsterdam—where he played an immortal detective—before the stars aligned for Westeros. When he finally walked into the audition for Jaime, he knew the character was a "dick." His words, not mine. He loved that Jaime was a villain who didn't think he was a villain.
Why Nikolaj Coster-Waldau Was the Only Choice
The showrunners, David Benioff and D.B. Weiss, needed someone who could play "arrogant" without being "unwatchable."
Think about it. If you cast someone who is just a straight-up jerk, the audience never follows them through the redemption arc in Season 3. You need that glint in the eye. You need the charm.
Nikolaj brought this weirdly relatable identity crisis to the role.

- The Physicality: He’s right-handed. Jaime loses his right hand. Nikolaj actually had to learn how to do everything—fight, eat, move—with his left hand to make it look authentic.
- The Bath Scene: Ask any die-hard fan about the "Kingslayer" and they’ll point to the bathtub scene with Brienne of Tarth. That’s where the kingslayer game of thrones actor stopped being a meme and became a tragic hero.
- The Chemistry: His rapport with Gwendoline Christie was lightning in a bottle. It wasn't just scripted; they genuinely riffed off each other, which made that slow-burn relationship feel earned.
It wasn't all easy, though. During those middle seasons, Nikolaj had to wear various prosthetic "stumps." He’s mentioned that the logistics were a nightmare—trying to hide his actual hand down his trousers or tucked away in his armor while filming intense action scenes.
What the "Kingslayer" Is Doing in 2026
Life after the Iron Throne hasn't been about sitting around. Nikolaj has pivoted hard into "prestige" projects and advocacy.
If you haven't seen Against the Ice on Netflix, you’re missing out. He didn't just star in it; he co-wrote and produced it. It’s a grueling true story about Danish explorers trapped in Greenland. It’s a far cry from the silk robes of King's Landing. He spent weeks filming in sub-zero temperatures, actually freezing his face off for the sake of the shot.
And then there's his latest massive swing: King & Conqueror.
Released recently, this series sees him playing William the Conqueror. It’s almost poetic, isn't it? He went from playing a man who killed a king to playing a man who defined what it meant to be one. He’s also been serving as a UNDP Goodwill Ambassador, focusing on climate change—something he became passionate about after spending so much time in Greenland (his wife, Nukâka, is a former Miss Greenland, after all).

The Misconceptions We Still Have
People always ask him if he hated the ending. You know the one—Jaime heading back to Cersei and dying under a pile of bricks.
While the internet melted down in 2019, Nikolaj remained surprisingly defensive of it. He’s gone on record saying it made sense for the character. Jaime was an addict, and Cersei was his drug. You don't always get the "happily ever after" with Brienne just because it feels good.
He’s also addressed the "recasting" rumors that occasionally pop up in weird corners of the internet. No, there was never another actor. He didn't "replace" anyone in the pilot. He was the guy from day one.
Actionable Takeaways for Fans
If you're looking to follow his career beyond the gold armor, here is how to navigate the Coster-Waldau filmography:
- Watch "Headhunters" (2011): This is a Norwegian thriller. It is arguably one of the best heist movies of the last 20 years. Nikolaj plays a high-end recruiter who is also a specialized art thief. It's tense, smart, and shows why he was cast as Jaime in the first place.
- Check out "Shot Caller": He plays a businessman who goes to prison and has to become a hardened gang member to survive. The physical transformation is insane.
- Follow "An Optimist’s Guide to the Planet": This is his documentary series. If you want to see the real Nikolaj—funny, slightly nerdy, and deeply concerned about the world—this is the one.
The kingslayer game of thrones actor has managed to do what very few "franchise" stars do: he escaped the shadow of his most famous character. He isn't "Jaime Lannister" anymore; he's a writer, a producer, and a legitimate powerhouse in international cinema.
Next time you rewatch the series, pay attention to his eyes in the background of scenes where he has no lines. That’s where the real acting is happening. He was never just the man who killed the Mad King; he was the man trying to survive his own reputation.
