Fans and the director of The Witcher: Sirens of the Deep have praised Doug Cockle for returning as Geralt of Rivia. In an interview with Animation Scoop, filmmaker Kang Hei Chul revealed his excitement about Cockle’s performance and shared insights about the anime movie.
He recalled being amazed during Cockle’s first recording session.
I remember when Doug first delivered his read in the recording studio – it blew all of our minds, All of our concerns and stresses about finding Geralt’s voice completely vanished. What did I enjoy the most? He was undeniably perfect – irreplaceable, in fact. He is truly one of a kind. During the recording sessions, he naturally took the lead among us because he understood the character in every sense.
Hei Chul said

Hei Chul, who directed The Witcher: Nightmare of the Wolf, praised Doug Cockle’s performance in the upcoming The Witcher: Sirens of the Deep.
His masterful acting not only brought Geralt to life but also inspired me in ways I hadn’t expected, He didn’t simply deliver lines; he captured Geralt’s inner struggle, composed judgment, and even his warmth and humor that subtly emerge from time to time. He embodied every nuance, from Geralt’s breath and gestures to his complex emotional depth.
Hei Chul shared
He masterfully conveyed Geralt’s humanity and emotions while preserving his unyielding strength, achieving a perfect balance that transcended mere performance — he became Geralt. Once again, he proved his irreplaceable worth, solidifying my conviction that he is the one true Geralt of the animated world.
Hei Chul continued
The movie is set to premiere on Netflix on February 11, 2025, fitting between Episodes 5 and 6 of The Witcher Season 1. Cockle, who voiced Geralt in the Witcher video games, takes over the role in the anime after Henry Cavill left the live-action series. Joey Batey (Jaskier) and Anya Chalotra (Yennefer) will reprise their roles in the anime, while Liam Hemsworth will play Geralt in Seasons 4 and 5 of the live-action series, with Season 4 expected to release in 2025.
The official description of The Witcher: Sirens of the Deep states:
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 an all-out war.
The movie is inspired by the short story A Little Sacrifice from Sword of Destiny by Andrzej Sapkowski, the author of The Witcher series. Meanwhile, CD Projekt RED is developing The Witcher IV, where Geralt’s adoptive daughter, Ciri, will be the main playable character.
