Joe Manganiello just goes ahead and says all the cool bad guy stuff he would have done in Ben Affleck's Batman movie
Manganiello's Deathstroke would have apparently subjected Affleck's Bruce Wayne to "a superhero version of David Fincher’s The Game."

You have to feel for Joe Manganiello, a victim of what we’ve come to think of as “Whoops, the people who made our after-credits stinger for this superhero movie sure got a little too excited, huh?” syndrome. (Other recent sufferers include Harry “I played Thanos’ brother for 60 seconds” Styles and Mahershala “Really, you can’t do better than a voice cameo in six years?” Ali, both courtesy of Marvel’s Eternals.) Manganiello, for his part, was all set to be a pretty major part of the previous, now-crumbled iteration of the DC Comics movie universe, popping in to the last few minutes of Justice League (both versions) to play prominent bad guy Deathstroke, in a role that was supposed to get fleshed out by Ben Affleck’s standalone Batman movie. But since that film died even before the rest of the DCEU did, Manganiello is apparently figuring, hey, fuck it: Why not just tell people about all the cool shit he would have gotten to do?
