Riley plays a seminal role in Ellie’s development and history, as seen in The Last of Us: Left Behind, an expansion from the first game that jumps between events set during the campaign and the past.
Riley was also in The Last of Us: American Dreams, the prequel comic penned by Faith Erin Hicks and Neil Druckmann.
It’s not completely clear exactly what parts the Last of Us HBO series will be adapting from the game.
According to Deadline, Reid, known for her work in Euphoria and A Wrinkle in Time, will portray Riley Abel.
