HBO Max announced the renewal of the series even before the release of the second season (expected on April 13, 2025). What can viewers expect from the upcoming episodes?
The events of the third season will unfold five years after the events of the first. The main stars, Pedro Pascal and Bella Ramsey, will return to their roles as Joel and Ellie, and the cast will be joined by Kaitlyn Dever, Isabela Merced, and Jeffrey Wright.
The show's creators, Craig Mazin ("Chernobyl") and Neil Druckmann (the original game's author), initially planned to split the events of "The Last of Us Part II" into several seasons due to its scale.

In my opinion, the series has one or two more seasons before the end of 'Part II'. Filming is becoming more challenging because each episode is becoming more extensive.
Let's recall that the series, based on the iconic 2013 video game from Naughty Dog, tells the story of smuggler Joel and girl Ellie, who travel across post-apocalyptic America in search of a cure for a deadly fungal virus that turns people into zombies.Craig MazinThe final results exceeded even our most ambitious expectations thanks to our collaboration with HBO and the impeccable work of the cast and crew.
The first season of "The Last of Us" became one of the highest-rated dramatic series in HBO's history and was nominated for 24 Emmy Awards. In the finale, Joel saves Ellie from the "Fireflies" group, who planned to use the girl to create a vaccine for the virus (Ellie is immune).
