Battle for Castle Itter: The True Story Behind Tubi's New Action Film

American soldiers and German Wehrmacht troops fighting side by side — against the SS — and it's all based on real events.

Remind Me

JUNE 8, 2026

May 5, 1945. The war in Europe is two days from ending. A small unit of U.S. soldiers rolls up to an Austrian castle where the SS has trapped a group of French VIPs, tennis stars, former prime ministers, a general, and decides the only way out is to fight alongside the Wehrmacht troops already holding the perimeter. This is not a premise someone invented. It happened. And The Battle for Castle Itter is the film that finally puts you inside it. The setup sounds like a pitch that got rejected for being too on the nose, but history didn't care about that.

The Cast

Aleksandar Trmcic

Trmcic carries the weight of a unit that has no business being here, fighting a battle that technically doesn't need to happen anymore. He's the axis the whole operation turns on, the soldier who has to hold together men who don't trust each other long enough to survive one more day.

Daniel Grogan

Grogan plays into the friction at the heart of the film, the American side of an alliance nobody wanted and nobody planned for. There's a scene where the distrust between allies is more dangerous than the enemy outside the walls, and Grogan is right in the middle of it.

Laurent Rouy

Rouy is one of the French prisoners, which means he's simultaneously the reason this mission exists and the biggest source of tension inside the castle. The people being rescued are not passive. They have opinions about how this should go.

Boris Lukman

Lukman represents the other half of the impossible alliance, the German side. He's not playing a villain or a redemption arc. He's playing a soldier who made a calculation and is now stuck living it out under fire.

“The war ends in two days. Try not to die before then.”

Why Watch It

The reason this story works is the same reason it sounds fake: the stakes are completely inverted. The SS isn't fighting to win the war, that's already lost. They're fighting to make sure the prisoners don't survive to tell anyone what happened. Which means the Americans and the Wehrmacht are defending the same castle, sharing the same walls, pointing guns in the same direction, while every instinct they have is telling them the guy next to them is the enemy. That tension doesn't go away just because the situation demands cooperation.
