Screen Rant has learned DC Entertainment President & CCO Geoff Johns will produce Harley Quinn vs. The Joker, a spinoff from 2016's Suicide Squad.

While no other details on the project are known, there's possibility some light will be shed on the report during Saturday's Warner Bros. presentation at Comic-Con International in San Diego. The panel is rumored to include a new trailer for Justice League, along with a first look at Aquaman and an update on the sequel to Wonder Woman.

Anticipation for the Hall H presentation is high, especially after this afternoon's report that the studio plans to transition from Ben Affleck as Batman to another actor in the role.

Robbie is lined up to reprise her role as Harley Quinn in director David Ayer's Gotham City Sirens, appearing alongside DC antiheroines Catwoman and Poison Ivy. Althoug there's been speculation that Leto might appear in that film as The Joker, the actor remains tight-lipped.

“I have no idea,” recently said. “Y’know, I can’t confirm — maybe I know — but I can’t confirm or deny. There are a lot of moving parts for that stuff, and we’ll see what happens next.”
