Why Liam Hemsworth Is Not The One Voicing Geralt In The Witcher’s New Movie
Liam Hemsworth’s Geralt Debut Will Be In Season 4
If not Henry Cavill voicing Geralt inSirens of the Deep, that leaves the question of why his replacement in Netflix’sThe Witcherisn’t voicing Geralt, either. The announcement of Liam Hemsworth playing Geralt arrived at the same time as that of Cavill’s departure, so there was no wait for the audience between Cavill’s exit and Hemsworth’s casting – however, it’s unknown how long it passed behind the scenes between these two, soit’s possible that Netflix spent a long time looking for the next Geralt.
It’s possible thatSirens of the Deepwas already in production and with its cast locked in when Hemsworth was cast.
As mentioned above, it’s unknown which part of its development and productionSirens of the Deepwas in when the announcements of Cavill’s departure and Hemsworth’s casting were made, as well as when Hemsworth was cast. It’s possible, then, thatSirens of the Deepwas already in production and with its cast locked in when Hemsworth was cast, thus not making it possible for him to voice Geralt.
Even if Hemsworth had been cast (and his casting announced) beforeSirens of the Deep, it’s unlikely Netflix would have given him the role of Geralt in the movie. That would have been Hemsworth’s debut as Geralt, and it’s very different to voice the character than playing him in live-action.Hemsworth’s Geralt debut being inThe Witcherrather thanSirens of the Deepensures that the attention will go to the main show, which has been struggling in recent seasons while allowingSirens of the Deepto be its own thing.
Is Geralt From The Witcher: Sirens Of The Deep The Same One From The Netflix Show?
It’s All Connected In The World Of The Witcher
A big question aboutSirens of the Deepis its connection to the main TV show and if it’s set in the same timeline. Just like the animated prequel movieNightmare of the Wolfand the prequel miniseriesBlood Origin,Sirens of the Deepis set in the same continuity asThe Witcher. As revealed byNetflix,Sirens of the Deepis set between episodes 5 and 6 ofThe Witcherseason 1, meaning that the Geralt in the movie is the same as Cavill and Hemsworth’s in the main series – and, of course, that also goes for Jaskier and Yennefer.

Sirens of the Deep’s place in theWitchertimeline also explains why Ciri isn’t a main character in it, despite being so in the main show and her strong connection to Geralt.The Witcherseason 1, episode 5, “Bottled Appetites”, follows Jaskier and Geralt as they encounter a Djinn, which leads them to meet Yennefer. This is the beginning ofGeralt and Yennefer’s relationship, and episode 6, “Rare Species”, sees them briefly reconciling before parting ways again. It’s worth noting thatThe Witcherseason 1 was told in a non-linear style, and these events happened before Ciri had to escape.
The young Geralt briefly seen inNightmare of the Wolf, Cavill’s version in the first three seasons ofThe Witcher, Geralt inSirens of the Deep, and Hemsworth’s version in seasons 4 and 5 are all the same, just played by different actors.Sirens of the Deepis a complement toThe Witcher, and will help the audience get to know Geralt a bit better.
