Mats Steen and the cast of the new film

It's not every day a story from a home in Drammen makes the whole world cry. And it's definitely not every day that such a story ends up being told by one of the most star-studded casts we've ever seen in a Norwegian production. Because now it's official: the life of Mats Steen, the boy who lived his great adventure through his World of Warcraft character Ibelin, is becoming a feature film – with the one and only Anthony Hopkins on the cast list.

I've been following this story closely since the poignant documentary came out a few years ago. It was impossible not to be moved by the story of the boy with Duchenne muscular dystrophy, whose parents, Robert and Trude, thought he was living a lonely life behind his bedroom door. That in reality, he was a pillar in an international network of friends, a mentor and a source of comfort for tens of thousands of other gamers – no one had any idea – until he suddenly passed away, just 25 years old, in 2014.

An Unprecedented Dream Cast

Now, the drama film is set to go into production, and director Morten Tyldum (The Imitation Game, Headhunters) has really pulled off a major coup. This is no longer just an award-winning documentary; this is a big, international production with serious weight behind it.

Rumours have been swirling for a while, but recently his father, Robert Steen, confirmed who is playing whom, and it's almost enough to make you want to pinch yourself. Here's the cast list that sends shivers down the spine of any film lover:

  • Anthony Hopkins takes on the role of Mats' grandfather. Two Oscars on his shelf, and he's on board. That says something about the strength of the script.
  • Charlie Plummer (whom we know from Looking for Alaska) will portray Mats himself.
  • Toni Collette (Hereditary, The Sixth Sense) becomes his mother, Trude.
  • Stephen Graham (Adolescence, Boiling Point) takes the role of his father, Robert.
  • Additionally, we see young rising stars like Isabela Merced (The Last of Us) and Maisy Stella (My Old Ass) in other key roles.

When influential Norwegian filmmakers call this a "dream cast" on Tyldum's Instagram post, it's easy to agree.

Back to the Roots in Drammen

What makes this extra special for those of us with local interest is that the film won't just be Norwegian – it'll be very Norwegian. Filming is scheduled to take place in Europe during the spring or summer of 2026, and everything points to it being set in Oslo and Drammen. It's in these streets that Mats grew up, and it's where the real magic happened, both in his life and afterwards when his family began publishing his blog, Musings of Life.

The screenplay is written by Ilaria Bernardini and Oscar-nominated Hossein Amini (Drive), and is based precisely on Mats' own words from the blog. That bodes well. This won't be a dry biography, but a glimpse into the mind of a guy who refused to let his body set limits on who he could be. As Morten Tyldum himself says: the film will go "inside Mats' head" in a completely different way than the documentary did.

A Legacy That Lives On

It's touching to think that his dad Robert was sitting here the other day answering questions from the press about his son once again. That he has to deal with the fact that Anthony Hopkins will portray his own father on screen. The Steen family has shown incredible strength in sharing this story, and they've done so with an openness that has touched millions.

The critically acclaimed documentary Ibelin received overwhelmingly positive reviews and was hailed by international critics as "a moving masterpiece." Now it's becoming a feature film with an even bigger canvas. And amidst all the Hollywood glamour, with stars like Hopkins and Collette, it's good to know that the heart of the film will still beat for a boy from Drammen who found community, friendship and meaning in a digital world. It's simply going to be amazing to see what Tyldum achieves when the cameras start rolling next year.
