The Witcher: How Liam Hemsworth Prepared to Replace Cavill as Geralt

Geralt didn’t just change faces—he evolved. Here’s how Liam Hemsworth rebuilt The Witcher from the inside out.

In this Collider breakdown, we explore the physical, vocal, and emotional work that shaped his version of Geralt. From London-based sword choreography and rain-drenched fight rehearsals to endurance training designed to balance muscle with mobility, Hemsworth’s prep was far more than a basic superhero bulk-up. His transformation included full immersion in Sapkowski’s novels, The Witcher games, and Cavill’s earlier seasons to ensure continuity without imitation.

We also unpack how Netflix smoothed the recast: reshooting key memories with Hemsworth, using a lore-friendly meta opening, and crafting a transition that feels intentional rather than abrupt. Showrunner Lauren Hissrich encouraged him to lean into a version of Geralt that’s a little funnier and more vulnerable—giving Season 4 space for fresh emotional beats and long-tail character development.

Whether you’re curious about the fight training, the wig tests, or how Hemsworth synced his voice, movement, and character psychology, this episode reveals what it really takes to step into one of modern fantasy’s most iconic roles.
