With Steven Spielberg’s Ready Player One currently putting its cast together, the film has added TJ Miller to its ranks.

The Hollywood Reporter has word that the Deadpool and Silicon Valley star will play an online troll named i-R0k in the upcoming adaptation of Ernest Cline’s best-selling novel. Miller joins a cast that includes Tye Sheridan, Olivia Cook, Simon Pegg and Ben Mendelsohn.

The synopsis for the source material reads:

Set in the near future, Ready Player One follows outcast teenager Wade Watts, who escapes from his bleak surroundings by logging in to the OASIS, a globally networked virtual utopia where users can lead idyllic alternate lives. When the eccentric billionaire who created the OASIS dies, he offers up his vast fortune as the prize in an elaborate treasure hunt. Along with gamers from around the world, Wade joins the adventure, and quickly finds himself pitted against powerful corporate foes and other ruthless competitors who will do anything, in the OASIS or the real world, to reach the treasure first.

At present, Spielberg’s Ready Player One is set for a March 30th, 2018 release.
