Doug Cockle returning to voice Geralt for new Netflix movie: Everything we know about The Witcher: Sirens of the Deep

It’s official, Doug Cockle is back to voice Geralt for a new animated installment set within The Witcher universe! During Geeked Week 2023, Netflix officially confirmed the new animated movie, The Witcher: Sirens of the Deep, the second animated project after The Witcher: Nightmare of the Wolf.

As debates rage on about Henry Cavill and Liam Hemsworth playing the live-action Geralt, it’s nice to that a universally beloved guy is going to be voicing the titular witcher. Cockle, of course, famously voices Geralt of Rivia in all three of CD Projekt Red’s video games (and the Gwent game!). His voice can also be heard in other acclaimed titles like Baldur’s Gate III (Bhaal) and Alan Wake II (Robert Nightingale).

Sirens of the Deep doesn’t have a release date yet, but the announcement video and official teaser both say that it will be released in late 2024, so likely not until the second half of the year. That’s nice because odds are we won’t get The Witcher season 4 until 2025 at the earliest, so at least we’ll get some new Netflix Witcher content next year!

What is The Witcher: Sirens of the Deep about?

For book readers, you’ll already be familiar with the Sirens of the Deep storyline as it’s based on the short story “A Little Sacrifice” from the Sword of Destiny collection by Andrzej Sapkowski and introduces the fan-favorite character Essi Daven, a troubadour who has a sibling-like relationship with Dandelion (Jaskier).

If you played The Witcher 3: Wild Hunt, you might notice that the character Priscilla is basically the game’s version of Essi, though her relationship to Dandelion in the games is romantic whereas it’s not in the book.

You can watch the trailer below, which teases our first look at Cockle’s animated Geralt, Jaskier, and Essi (who has trademark long blond hair covering one eye, a look that earns her the nickname “Little Eye”). It also looked like we got a quick glimpse of the mermaid Sh’eenaz and the duke Agloval, who both play important roles in the story.

Sirens of the Deep focuses on the monster hunter taking on a new job where he is assigned to investigate attacks occurring regularly in a seaside village. He finds himself drawn into a conflict between the village’s inhabitants and the merpeople living within the sea.

“A Little Sacrifice” didn’t show us the merpeople’s perspective, as it primarily focused on what was happening above-land. The teaser indicates that the movie will go deeper into the lore, as there’s a small clip where we see the merpeople assembling underwater.

Here’s Netflix’s logline:

"Geralt of Rivia, a mutated monster hunter, is hired to investigate a series of attacks in a seaside village and finds himself drawn into a centuries-old conflict between humans and merpeople. He must count on friends — old and new — to solve the mystery before the hostilities between the two kingdoms escalate into all-out war."

In the short story, Essi and Geralt have a complicated relationship with Essi forming feelings for Geralt, though they’re somewhat unrequited because, simply put, she’s not Yennefer. The whole thing is a little suspect because she’s meant to be quite young.

Sapkowski actually served as a creative consultant on the film, which is exciting. So hopefully he was able to provide input into the expansion of the merpeople.

Regarding the overall timeline of the Netflix Witcher-verse, the streamer confirms this story is chronologically set between episodes 5 and 6 of the first season.

Sirens of the Deep cast

Besides Doug Cockle returning to voice Geralt, fans can also expect to hear The Witcher stars Joey Batey and Anya Chalotra back to voice Jaskier and Yennefer, respectively. From what I remember of “A Little Sacrifice,” Yennefer does not actually appear in the story, but they must be adding her into it somewhere, perhaps via flashback.

Additionally, Man of Steel and Batman v Superman: Dawn of Justice star Christina Wren will voice the bard Essi Daven. No other cast members have been announced just yet.

Regarding his return to the Continent, Cockle told Netflix:

"“I am super excited to announce my return to the world of The Witcher voicing Geralt of Rivia once again,” Cockle told Netflix. “I’m thrilled to be able to share this next chapter of the White Wolf’s journey with fans of the Witcher universe. Mire taedh aen stráede!”"

Sirens of the Deep is produced by The Witcher showrunner Lauren Schmidt Hissrich and will be written by Mike Ostrowski and Rae Benjamin, who have both also written for the live-action series.

Additionally, Nightmare of the Wolf storyboard artist Kang Hei Chul steps in to direct Sirens of the Deep. It is produced by Studio MIR, the company who produced the previous animated Witcher film, The Legend of Korra, and Voltron: Legendary Defender.

Sirens of the Deep is coming to Netflix in late 2024. Stay tuned to Netflix Life for more details on what to expect from the animated film!
