The latest unlikely development in the saga of Zack Snyder's Justice League is that, against all the odds, Jared Leto is returning as the Joker. Though his performance in 2016's Suicide Squad was widely panned at the time, the actor's turn as the Clown Prince of Crime has been as reevaluated in the past four years as Snyder's directorial efforts have and now he's taking part in the reshoots for the HBO re-release of the team-up movie that are currently underway.
