The Witcher: Sirens of the Deepis the latest addition to Netflix’s fantasy franchise, and the anime movie is set between episodes 5 and 6 of the first season of the live-action show — so it features a few familiar faces throughout its run. Geralt is the most obvious returning character, asThe Witcher’s lead is at the helm of the new film.Netflix’sWitchermovie is based onAndrzej Sapkowski’s short story, “A Little Sacrifice,” which places Geralt in the middle of a conflict between the humans of Bremervoord and the merpeople of Ys.
The Witcher: Sirens of the Deepdigs deeper into Geralt’s travels around the Continent and monster-hunting, moving away from the main story for a bit. But the film still hasconnections to Netflix’s main show, as the characters it features are the same ones who drive the live-action story forward. While Ciri is absent fromSirens of the Deep,Geralt isn’t the only person fromThe Witcherto appear in the film. And some characters are even played by the same actors as their live-action counterparts, driving home the overlap between projects.
3Geralt Of Rivia
Voiced By Doug Cockle
Geralt is the star of Netflix’s newWitchermovie, even if he’s thrown into the main conflict by chance. The anime film seeks to show more of his time wandering the Continent with Jaskier, as well as more of the monster-hunting the character is known for. AndSirens of the Deep’s Geralt looks and acts just like his live-action counterpart — a relief since he’s not voiced byHenry Cavill in Netflix’s new movie. This isn’t a surprise, asHenry Cavill announced his departure fromThe Witcherback in 2022. Season 3 marked his final performance as the show’s lead.
The Witcher: All 6 Actors Who Have Played Geralt Of Rivia
The world of The Witcher has seen different actors as Geralt in the books' many adaptations, all of them bringing a unique touch to the character.
This meant a different voice actor for Geralt was inevitable, but surprisingly, Netflix didn’t go with Liam Hemsworth — whowill replace Cavill in the live-action series— forSirens of the Deep. Instead,The Witcher’s new movie cast Doug Cockle in the role. Cockle voices Geralt inThe Witchervideo games, soCavill’s first Geralt replacementoffered a solid alternative to both live-action stars. Geralt’s original English voice actor captures all the mannerisms of the character viewers know and love while continuing to make the movie’s lead his own.
While hearing anyone other than Cavill in the role may still be jarring, Cockle does a great job of bridging the gap betweenThe Witcher’s live-action Geralts.
While hearing anyone other than Cavill in the role may still be jarring, Cockle does a great job of bridging the gap betweenThe Witcher’s live-action Geralts. Andhe’s surrounded by impressive talent inThe Witcher: Sirens of the Deep,including two stars who reprise their roles from the main series.
2Jaskier
Voiced By Joey Batey
While Geralt is portrayed by a new actor inThe Witcher: Sirens of the Deep,Jaskier is still played by Joey Batey. That’s why the bard sounds similar to his live-action counterpart, and it’s fitting that Batey returns for a film meant to take place in the midst ofThe Witcherseason 1. Batey’s portrayal of Jaskier has easily become one of the best parts of the main series, and he continues to shine in Netflix’s 2025 film.Sirens of the Deepoffers a more in-depth look at Jaskier’s backstory, too, showing viewers where he came from and why he left.
2025 Could Be A Bigger Year For The Witcher Franchise Than You Realized
The Witcher season 4 is expected to arrive in 2025, but this year could revitalize the franchise overall with multiple releases coming down the pike.
Jaskier’s dynamic with Geralt continues to be a highlight of the franchise in the newWitchermovie, even withSirens of the Deepchanging Geralt actors. The characters have just as much chemistry in this new release, andBatey’s voice acting grounds the film in the greater franchise, giving viewers something familiar to latch onto. He’s not the only returning cast member fromThe Witcher,but he has the more prominent story of the two stars reprising their roles.
1Yennefer Of Vengerberg
Voiced By Anya Chalotra
Yennefer of Vengerberg appears sporadically throughoutThe Witcher: Sirens of the Deep, when Geralt is remembering his relationship with her. However, Yennefer doesn’t play a role in the main story in the same way Jaskier does, so her presence is a lot less prominent throughout the film. Even still,Sirens of the Deepoffers more of Geralt’s perspective of their relationship, which adds an interesting layer to season 1 of the live-action show. There are also a few comical moments that reiterate Jaskier’s feelings about Yennefer.

It’s a shame the movie doesn’t feature more of her, though the actor’s brief appearances ramp up the excitement forYennefer’s story inThe Witcherseason 4. And like Jaskier’s return, Yennefer’s scenes help connectThe Witcher: Sirens of the Deepto the main Netflix series, making the overall franchise feel more cohesive.
