Watch Real Performers Become ‘Resident Evil’s’ Viral Rolling “Katamari Monster”

I’ve been meaning to share this, but with all the news flying around lately, it slipped through the cracks. And this is way too fucking cool to miss.

Resident Evil movement coordinator Jakub Hudlický has shared behind-the-scenes footage showing the physical work that went into developing the movement of Zach Cregger’s grotesque “Merged Monster,” the creature you’ve probably seen referred to as the “Katamari Monster.”

The video shows performers strapped together, facing different directions, as they collectively tumble across a rehearsal space. Arms and legs swing through the air while the group rotates as one tangled body, then somehow lands upright again.

It’s an incredible bit of coordination. Even without the creature’s finished appearance, the movement is already deeply unsettling.

Writing on Instagram, Hudlický explained that the exploration began in July 2025, when he teamed up with Filmka Stunt Team and Cirk La Putyka to answer one question:

“How can the Merged Monster moooove?”

Hudlický also credited Maya Kvetny Casting and Stillking Films with bringing him onto the project.

To be precise, this is a look at the movement-development process, rather than proof that every shot of the finished creature was achieved practically. What makes it fascinating is seeing performers physically work out how this impossible collection of bodies could move.

With the rise of AI filmmaking, I worry that this kind of hands-on experimentation could become less common. Watching people get together and figure out how to turn their bodies into a rolling nightmare is such a wonderful reminder of the creativity involved in making these movies.

Give these performers some love. This is the kind of behind-the-scenes footage I could watch all day.
