Earlier this year, shortly after the premiere of the first season of the live-action series The Last of Us, HBO announced that they would be renewing the show for a second season. After the first season concluded last week, writer Neil Druckmann revealed on his personal Twitter today that production for the second season has already begun.
By the way, he once stated in an interview that if there were to be a second season of The Last of Uss, the storyline might cover the events of the game The Last of Us Part II.
