The Last of Us has been in development since March 2020, and HBO moved forward with a series order in November.
HBO already has another high-profile project releasing in 2022, but I think we can be confident that The Last of Us will score plenty of viewers regardless of when the first Game of Thrones spinoff debuts.
There is no official word of when viewers can expect to see the video game adaptation premiere as a TV show, but the series is making enough progress that it’s possible the first episode could debut in late 2021 or early 2022.
