Netflix did release an official full Season 4 trailer, but on 2025-10-07, not in September 2026; the season itself premiered on 2025-10-30.
Netflix leaves The Witcher fans waiting on old footage
Online claims of a new 2026 trailer point to video released a year ago.
In a nutshell
Reports circulating online about a newly released trailer for The Witcher Season 4 are reviving promotional video that is already a year old. Netflix published the full trailer in October 2025, and all eight episodes of that season debuted weeks later. The actor handover from Henry Cavill to Liam Hemsworth has already occurred on screen, meaning genuine future updates will concern the upcoming fifth and final season.
Highlights
- Liam Hemsworth was announced as Henry Cavill's replacement in October 2022.
- Netflix released its first moving footage of Hemsworth as Geralt on May 22, 2024.
- The official full trailer for Season 4 was published on October 7, 2025.
- All eight episodes of Season 4 premiered on Netflix on October 30, 2025.
- The series will conclude with Season 5, which was filmed back-to-back with Season 4.
From the Editor’s Diary
Old promotional videos often resurface online as breaking news, but a quick check of an existing streaming library confirms whether a season has already aired.

In short
Viewers checking for new footage of The Witcher are running into old releases passed off as fresh news. Netflix published the full trailer for Season 4 in October 2025, and all eight episodes of that season are already streaming.
This means future official updates will focus on the fifth and final season, which will conclude the fantasy adaptation.
That next step is near-certain because Netflix filmed the final chapter alongside the fourth, though the company has not yet set a premiere date for it.
How it unfolded
Netflix replaces its leading man
The journey toward Season 4 started when Netflix renewed the fantasy series and confirmed that Liam Hemsworth would take over the role of Geralt from Henry Cavill. Both performers released statements confirming the switch. Entertainment trade outlets carried the news that afternoon, establishing the cast change as the central focus of the fourth season long before filming began.
Filming begins and reveals the new lead
Work on Season 4 began in the United Kingdom alongside plans to film a fifth and final season back-to-back. One month into production, Netflix shared its first video of Hemsworth in costume as Geralt. The preview confirmed that the eventual full trailer was not his first public appearance in character.
Sports broadcast unveils combat and a date
Netflix aired an extended action preview during its live boxing broadcast of Canelo Álvarez versus Terence Crawford. The clip showed Hemsworth fighting a ghost-like wraith and revealed that Season 4 would arrive on October 30. Additional still images and details followed on the company's promotional site the next day.
The full trailer outlines the season
The full trailer arrived on October 7, 2025, running two minutes and 12 seconds. It detailed the core plot: Geralt, Yennefer and Ciri are separated across a continent at war, while the villain Vilgefortz gathers an army. The video also introduced Laurence Fishburne as Regis and confirmed the October 30 streaming date across major entertainment outlets.
Completed episodes render the video archival
Season 4 debuted on October 30, 2025, turning the promotional clip into an archive listing for an existing season. Netflix confirmed by December that all eight episodes were available to stream. Online claims citing a new September 2026 trailer refer to existing promotional material from 2025 rather than an unreleased season.
Where things stand
Netflix released the official trailer for The Witcher Season 4 on October 7, 2025, ahead of the season premiere on October 30, 2025. All eight episodes are available to stream, and earlier clips of Liam Hemsworth in character had already debuted in 2024 and mid-2025.
Internet links describing a brand new Season 4 trailer in September 2026 do not match company announcements or streaming records. While Netflix has confirmed that a fifth season will conclude the series, any upcoming marketing will focus on that final chapter rather than reintroducing Season 4.
