2016 was a much simpler time. It was a time before disasters like the Coronavirus pandemic and the release of Justice League. Back in August 2016 principal photography was still taking place on Justice League under the direction of Zack Snyder and Ben Affleck was still attached to write, direct and star in The Batman.
At the time Affleck dropped the below footage of Deathstroke on social media, something which got the fanboys excited But it was all for naught.
A little over a year later Justice League was re-shot and re-tooled by Joss Whedon and it opened to lacklustre box office and Ben Affleck later bailed on The Batman. Joe Manganiello made a brief appearance as the character of Deathstroke at the tail end of Suicide Squad and an ill-fated Deathstroke film was in the planning stages with The Raid‘s Gareth Evans set to direct. That was the end of that.
