Until now, the Justice League has been a loose association of superpowered individuals. But when they are swept away to Warworld, a place of unending brutal gladiatorial combat, Batman, Superman, Wonder Woman and the others must somehow unite to form an unbeatable resistance able to lead an entire planet to freedom.
Unfortunately the movie Justice League: Warworld is not yet available on HBO Max.
