Zack Snyder says it was "important for fans" to see the DCEU Batman (Ben Affleck) and Joker (Jared Leto) collide in Zack Snyder's Justice League, where Leto reprises his role for the first time since 2016's Suicide Squad. When revealing the first look at a world-weary and reimagined Joker from an apocalyptic possible future — the Knightmare sequence first glimpsed in Batman v Superman: Dawn of Justice — Snyder described the meeting as a scene about "Joker talking directly to Batman about Batman," where the psychopath psychoanalyzes the Dark Knight "about who he is and what he is."
