Netflix’s The Witcher: Sirens of the Deep is set to take fans on an exciting journey that remains true to the character of Geralt while also taking him to new places that push him into unfamiliar waters. Voiced once again by Doug Cockle, the legendary Witcher will step into a world that expands on his well-known persona without altering the core traits that have made him so iconic. With the upcoming anime film bridging a gap in The Witcher’s live-action timeline, viewers can expect both familiarity and intrigue as Geralt navigates a perilous conflict between humans and merpeople.
What makes Sirens of the Deep especially interesting is its commitment to maintaining Cockle’s established version of Geralt from the video games, rather than shifting the character to match the portrayal in Netflix’s live-action series. Yet, despite its adherence to the game’s voice and persona, the film still introduces new challenges, including the daunting task of communicating in a foreign, mystical language. These elements promise to make Sirens of the Deep an exciting addition to The Witcher’s ever-growing universe.
Doug Cockle’s Return as Geralt Brings a Familiar Voice in a New World
Doug Cockle Brings His Iconic Geralt to Netflix’s Anime Universe
Doug Cockle has been the definitive voice of Geralt of Rivia since 2005, having portrayed the White Wolf across multiple Witcher game titles. His involvement in Sirens of the Deep proves that the animated film is committed to staying true to the beloved character fans have come to know over the years. Unlike the live-action adaptation, where Henry Cavill and later Liam Hemsworth offer their own takes on Geralt, Cockle’s portrayal has been consistent and adored by fans.

Are you still upset about Henry Cavill’s The Witcher recast?
Henry Cavill played Geralt of Rivia in the first three seasons of the Netflix series The Witcher, but is being replaced by Liam Hemsworth for the fourth. Cavill left the series due to creative differences, and likely a little bit due to the response from audiences, but it is still upsetting to see. I am sure that Hemsworth will do a great job, but he has big shoes to fill. Despite the issues with the series, for me, Cavill was always a consistent positive thing about it. Perhaps season 4 will change my mind, but for now, everytime I think about this recast I get upset.
Rather than reworking the character to fit Netflix’s established tone, the film’s creators allowed Cockle to bring his Geralt to life in its purest form. In his own words, the production team never asked him to alter his portrayal and instead, they encouraged him to embody the same rugged, gruff-voiced Witcher fans love. This decision provides a sense of continuity between the games and the animated film, reinforcing the idea that Geralt’s character is timeless, no matter the medium.
While some might expect Sirens of the Deep to incorporate elements from the live-action series, it instead embraces the dark, atmospheric essence of the game franchise. This move not only appeals to long-time players but also gives newcomers a glimpse into what has made The Witcher games so revered over the years.
Geralt’s Unique Challenge of Merspeak and Diplomatic Struggles
Geralt’s Newest Battle? Mastering the Language of the Deep
Despite staying true to his established character, Geralt will still face new challenges in Sriens of the Deep, one of which involves learning a unique form of communication. With the film’s main conflict revolving around tensions between merpeople and humans, Geralt is forced to navigate diplomatic waters, both figuratively and literally. One of the most intriguing aspects of this storyline is the introduction of “merspeak,” a language that presents a completely new challenge for the Witcher.
Doug Cockle has expressed how difficult it was to voice Geralt speaking merspeak, emphasizing that it was one of the more demanding aspects of the role. Given Geralt’s usually terse and action-driven nature, seeing him attempt to communicate in an unfamiliar tongue adds an unexpected layer of depth to his character. This linguistic struggle offers a rare moment of vulnerability for Geralt, proving that even the most battle-hardened warriors can face obstacles outside of combat.
By introducing merspeak, Sirens of the Deep expands on The Witcher’s world-building in a way that has not been fully explored before. It shows Geralt’s versatility, not just as a monster hunter, but as a mediator between worlds. This new and thoughtful development helps to keep the character dynamic while maintaining his signature personality, making the film a worthwhile addition to The Witcher’s extensive lore.

With Henry Cavill stepping down and Liam Hemsworth preparing to take over as Geralt in season four, many fans have speculated on the series’ direction. However, Cockle’s continued involvement in the animated universe suggests that the Witcher brand is staying grounded in its roots despite these big changes.
The decision to bring Cockle back for the anime film shows that Netflix values the legacy of the games, which could have more implications for the franchise’s and Cockle’s future. Especially with The Witcher 4 currently in development. Fans who have followed his journey through the games may find Sirens of the Deep to be a comforting bridge between past and future adventures. As Netflix continues to expand The Witcher’s universe, this film serves as a reminder that some portrayals of iconic characters are simply irreplaceable.
