Prime Video’s lavish historical epic with a HotD star is your next weekend obsession

You know the drill by now: put a bloke in chain mail, plonk a castle behind him, get a couple of shaggy-haired aristocrats having a heated debate about succession—and suddenly half the internet reckons they’ve stumbled on the new Game of Thrones, or at the very least, the next best thing to it. Ever since Thrones and its prodigious spawn House of the Dragon made dodgy wigs and muddy backdrops the standard template for medieval telly, every ambitious historical epic gets stuck with the comparison whether it fits or not.

King & Conqueror has been grappling with that particular headache ever since it dropped on BBC One in 2025 and then made the jump to Prime Video. Frankly, I’d wager that whole Thrones shadow has nicked the show a fair chunk of the audience it deserves. People loaded it up expecting fire-breathing lizards and shadowy prophecies; what they actually got was something more grounded, arguably even more compelling. What you’ve got here is the slow implosion of a partnership between two massively ambitious men, both of them pulled towards a crown neither went out looking for.

It’s eight episodes long, by the way. If you’re staring at your watch waiting for House of the Dragon to resume but can’t stomach another cookie-cutter fantasy, this one’s worth your time.

Rivals Played by Familiar Faces

Here’s your main event: Nikolaj Coster-Waldau – the very same who spent eight years as Game of Thrones’ perpetually conflicted Jaime Lannister – lands here as William, Duke of Normandy. But if you’re expecting another morally ambiguous soul search, you’re barking up the wrong tree. William is unwavering from the start. He is cold, patient, and absolutely convinced the English crown is his for the taking. There’s no redemption arc in sight, and Coster-Waldau’s performance is all the better for it. It’s easily his most chilling turn yet; the man doesn’t flinch, and you really believe he’d march over the corpse of his own best mate if it got him to Westminster Abbey.

James Norton, meanwhile, fresh off his stint as Ormund Hightower in House of the Dragon, steps into the boots of Harold Godwinson – and he’s got this reserved, completely relatable approach. He’s the sort you can’t help rooting for, even though, let’s be honest, we all know what happens to Harold at Hastings. Every decision Harold makes is more or less sensible, and yet you can feel the noose tightening with every one. The bloke is doomed, but Norton makes you care anyway.

The First Two Episodes Are a Slog – Stick With It

Now, cards on the table: the show takes its sweet time getting going. The first two episodes have all the pacing of a decrepit ox-cart. It’s worldbuilding, it’s necessary, but to be honest, I reckon loads of viewers bailed early and never saw what it blossoms into. But from episode three, it properly starts to cook, each new hour ratcheting up the tension. By the time William and Harold’s alliance finally shatters, all the groundwork is worth it, and the culminating battle at Hastings actually lands. Seven hours making you care about both men, and then it just chucks them at each other on a blood-soaked field. Miserable. Brilliant.

Who Else Is In the Mix?

• Eddie Marsan as King Edward – easily one of the best in the ensemble. He nails the whole vibe of a monarch watching calamity unfold, half-aware he started it all and resigned to what comes next.
• Juliet Stevenson as Lady Emma – the absolute definition of a composed schemer, never ruffled, always two moves ahead.
• Emily Beecham as Edith Swanneck – she’ll be familiar if you caught Into the Badlands, and here she’s quietly the ace in the deck. Most underrated performance of the show if you ask me.

What’s Not Quite There?

It’s not flawless, obviously. If you ask me, the friendship between William and Harold is a bit undercooked before everything goes up in flames. And as for Clémence Poésy’s Matilda, she starts tipping from fierce to outright bloodthirsty in a way that occasionally feels a bit pantomime. Still, those gripes only matter if you’re chasing another House of the Dragon. King & Conqueror isn’t that show. There’s no magic, no ancient prophecies, and the only dragons here are on the tapestry. It’s a stripped-back, properly medieval drama about ambition, power, and how two people could easily have ended up on the same side if it weren’t for a twist of fate.
