Netflix's The Witcher Season 4 Debuts Liam Hemsworth as Geralt

Netflix's fantasy series The Witcher returns for its fourth season on October 30, 2025, featuring Australian actor Liam Hemsworth as the new lead, taking over the role of Geralt of Rivia from Henry Cavill. The season, which marks a tonal refresh, balances Hemsworth's dry humor with dark storylines, as Geralt navigates separation from key characters Yennefer and Ciri while forming new emotional connections and travel companions. Showrunner Lauren Schmidt Hissrich highlighted the new energy Hemsworth brings and noted updates in the show's look, sound, and pace to match this fresh take. Alongside Hemsworth, Laurence Fishburne joins the cast as the vampire Regis, attracted by the show's diverse and non-traditional fantasy world. Netflix is releasing all eight episodes of Season 4 simultaneously, encouraging binge-watching, with a shorter total runtime than previous seasons. The season continues the serialized story based on Andrzej Sapkowski's books, aiming to engage both longtime fans and newcomers alike.
