Netflix's animated film The Witcher: Sirens of the Deep offers more monster-hunting action, and here's everything to know about Geralt's latest adventure. Continuing the streamer's expanded universe based on the Witcher books series by author Andrzej Sapkowski, The Witcher: Sirens of the Deep is the second animated film produced for the platform, and the first piece of Witcher media since the departure of Henry Cavill from the live-action series. The new animated feature delves deeper into the character's past and adapts a short story by Sapkowski which has never been brought to the screen before.

Henry Cavill's turn as Geralt in the live-action series had viewers streaming the show in droves, but Cavill left the role after The Witcher season 3. Netflix has hedged their bets though, and they not only produced a 2022 spinoff series entitled The Witcher: Blood Origin, but also a 2021 animated feature, The Witcher: Nightmare of the Wolf. Sirens of the Deep is a new step for the streaming giant, as the animated feature stars Geralt, who is played onscreen for the first time by someone other than Cavill.

The Witcher: Sirens Of The Deep Critical Reception

One Of Geralt's Lesser-Loved Adventures On Screen

After a long buildup for the return of Geralt in animated form, the reviews for The Witcher: Sirens of the Deep were somewhat disappointing. Though Screen Rant docked the movie for deviating too far away from the original source material while also sticking too closely to The Little Mermaid fairytale. Likewise, IGN deemed the movie "predictable" and the plot "boilerplate," though praise was given freely to Doug Cockle for his triumphant return as Geralt.

The Witcher: Sirens Of The Deep Cast

Doug Cockle Voices Geralt Of Rivia

The cast of The Witcher: Sirens of the Deep is an interesting mix of returning live-action actors, and newcomers from other corners of the larger franchise. First and foremost, Doug Cockle returned to voice Geralt of Rivia, and he provided the gruff White Wolf's vocals in games like Witcher 3. Coming from the cast of Netflix's The Witcher, Anya Chalotra reprised her role as Yennefer of Vengerberg, and she was ed by Joey Batey who is once again playing Jaskier. A newcomer arrived in The Witcher: Sirens of the Deep as Christina Wren plays the role of Essi Daven.

How Sirens Of The Deep Fits Into The Witcher Timeline

An Early Geralt Adventure

Instead of letting viewers guess about the timeline of The Witcher: Sirens of the Deep, Netflix used their Geekd Week platform to announce that the movie would take place between episodes 5 and 6 of The Witcher season 1. Even as the live-action series chugs forward in the timeline, the various extended universe movies and shows have the opportunity to go back and fill in the gaps that were not initially covered. Sapkowski himself didn't publish the Witcher books in order, and Netflix's approach somewhat mimics the fractured timeline.

The first season of The Witcher on Netflix adapted the short story collections The Last Wish and Sword of Destiny, though the series didn't include every tale that Sapkowski wrote. "A Little Sacrifice", the story that serves as inspiration for Sirens of the Deep, is pulled from the latter of the two collections, though it is unclear how Netflix is going to connect the animated film to what was happening in season 1 at the time. The stories in the collection are framed as Geralt's memories, which gives the film's creators a bit of elasticity when it comes to squeezing it into the timeline.

The Witcher: Sirens Of The Deep Trailers

The First Look At The New Witcher Movie

Netflix offered a brief glimpse at their new animated movie during Geekd Week in 2024 in the form of a teaser trailer. The half-minute clip is filled with scintillating soundbites from various characters, including Doug Cockle's return as Geralt. It also teased a fair amount of sex and violence, which has typically been a selling point for The Witcher franchise in general.

With only a few weeks until the movie arrived, Netflix dropped a full trailer for The Witcher: Sirens of the Deep in January 2025. Recounting the conflict between the humans and the merpeople, the trailer catches up with Geralt as he's trying to forget Yennefer and move on with Jaskier on another adventure. Settling the dispute is exactly the kind of action he needs, but he soon begins to suspect that something is amiss. The humans aren't being entirely honest, and a war is seemingly brewing between the land and sea.
