When the first season of Vikings wrapped up, we were all kinda left hanging. Ragnar was a rising star, but the world felt small. Then came Season 2. It didn't just expand the map; it blew the doors off the casting office. If you're looking back at the Vikings TV show season 2 cast, you’re basically looking at the moment a cult hit turned into a global obsession.
The shift was massive. We weren't just hanging out in the mud of Kattegat anymore. We were heading to Wessex, dealing with crazy Swedish Jarls, and watching kids turn into men overnight. Honestly, the way they handled the time jump was gutsy. Usually, when a show swaps actors for kids, it feels clunky. Here? It felt like destiny.
The Big Shakeup: Alexander Ludwig as Bjorn Ironside
The most "wait, what just happened?" moment of the Vikings TV show season 2 cast was easily the arrival of Alexander Ludwig. One minute Bjorn is a scrawny kid played by Nathan O'Toole, and the next, he's this literal giant walking through the woods.

Ludwig brought a different energy. He had that Hunger Games fame behind him, sure, but he actually looked like he could be the son of Travis Fimmel and Katheryn Winnick. It wasn't just the height. He captured that weird mix of "I want to kill you" and "I need my dad's approval" that defined Bjorn for the rest of the series.
- Actor: Alexander Ludwig
- Character: Bjorn Ironside
- Impact: Shifted the show from a single-hero narrative to a generational saga.
The Kings and the Cunning: New Faces in High Places
Season 2 introduced us to the man who would arguably become Ragnar’s greatest rival—and his weirdest friend. Linus Roache joined the Vikings TV show season 2 cast as King Ecbert of Wessex.
Roache was a masterstroke. While the Northmen were all about axes and honor, Ecbert was about baths, Roman ruins, and playing the long game. You’ve probably seen Roache in Batman Begins or Law & Order, but he was born to play this devious, charming king. His chemistry with Travis Fimmel was electric. They were two sides of the same coin: men who were too smart for the centuries they were born into.
Then there was King Horik. Donal Logue had been around in Season 1, but Season 2 is where he really started to rot from the inside. Logue played Horik with this simmering insecurity. He knew Ragnar was the better man, and watching that jealousy boil over was one of the best parts of the season.

The Villains We Loved to Hate
Can we talk about Jarl Borg? Thorbjørn Harr was terrifying. He didn't just want land; he wanted revenge. Harr, a Norwegian actor, brought a terrifyingly calm intensity to the role. That scene with the Eagle? Yeah, you know the one. That wouldn't have worked without Harr's performance. He made Jarl Borg feel like a genuine threat to Ragnar’s home, not just another guy in a leather vest.
The Women Holding It Together
Lagertha and Aslaug. The drama was real.
Katheryn Winnick continued to be the absolute backbone of the show as Lagertha. In Season 2, she had to reinvent herself. She went from a betrayed wife to a powerful Earl in her own right (shoutout to Earl Sigvard’s short-lived reign). Winnick’s physicality is always impressive, but her emotional range when she reunites with Ragnar is what sells the season.
On the other side, you had Alyssa Sutherland as Princess Aslaug. People loved to hate her because she "broke up" the main couple, but Sutherland played the role with a strange, ethereal grace. She wasn't a warrior, but she was a survivor. Her presence in the Vikings TV show season 2 cast added a layer of mysticism and political tension that the show desperately needed as it grew.
The Supporting Players Who Made the World Feel Real
Vikings thrives on its ensemble. You can't talk about the cast without mentioning the regulars who stepped up their game.
- Gustaf Skarsgård (Floki): This was the season where Floki’s loyalty started to look... let's say "questionable." Skarsgård is a genius at being both hilarious and deeply unsettling.
- George Blagden (Athelstan): Poor Athelstan. Blagden’s performance as a man caught between two gods—and two kings—is the heart of the season. His internal struggle is basically the show's thesis statement.
- Clive Standen (Rollo): Rollo starts the season as a traitor and ends it trying to find his soul. Standen’s physicality is unmatched, but he’s also great at looking like a kicked puppy when Ragnar won't talk to him.
- Jessalyn Gilsig (Siggy): She’s the ultimate survivor. Gilsig played Siggy with so many layers—was she helping Rollo, or was she just helping herself? You never quite knew.
Why This Specific Cast Worked
It’s all about the chemistry. You had actors from Australia (Sutherland), Canada (Fimmel, Ludwig), the UK (Blagden, Roache), and Scandinavia (Skarsgård, Harr). It was a melting pot. This mix of accents and acting styles created a world that felt vast and "other."
The writers knew what they had. They let the actors lead. For example, did you know Thorbjørn Harr actually pushed for his character to use two axes instead of a sword? He felt it made Jarl Borg more distinct. That kind of actor input is why these characters feel like people instead of just historical footnotes.

Practical Takeaways for Fans
If you're doing a rewatch or just catching up, keep an eye on these specific performance beats:
- Watch the eyes: Travis Fimmel is famous for his "crazy eyes," but watch how Linus Roache matches him in their scenes together. It’s a battle of the gazes.
- The Age Gap: Notice how the show uses makeup and hair to age Ragnar and Lagertha to make the jump to an adult Bjorn feel more believable.
- The Background: Look at characters like Torstein (Jefferson Hall). Season 2 is where the "inner circle" of Ragnar's friends really starts to solidify, making their later fates much more impactful.
Basically, the Vikings TV show season 2 cast was the perfect storm. It kept the core that we loved—Ragnar, Lagertha, Rollo—and added heavy hitters that forced the original stars to level up. It’s the season where the show stopped being a "History Channel experiment" and became a legendary drama.
The next step is to look closer at the historical figures these actors portrayed. While the show takes huge liberties with the timeline, the core personalities—the ambition of Ecbert, the legendary status of Bjorn, and the tragic conflict of Ragnar—are all rooted in the Sagas. Compare the show's portrayals to the historical records of the Great Heathen Army to see where the actors stayed true to the legends and where they brought something entirely new to the table.
