The Looper star, whose Dark Knight Rises character John Blake appeared to inherit the Batman mantle at the close of Christopher Nolan's blockbuster, is allegedly "solidifying" a deal to return as the superhero for 2015's Justice League.
According to HitFix, Gordon-Levitt and one other unnamed star from Nolan's Batman trilogy may appear in Justice League.
The site speculates that Henry Cavill's Man of Steel could feature in a cameo appearance from Gordon-Levitt's Batman. Zack Snyder hinted in a recent interview that his Superman reboot, which arrives next summer, may tie into Justice League.
If Gordon-Levitt appears as Batman in Justice League, it will mark the first time a big-screen Dark Knight's alter ego hasn't been Bruce Wayne.
Asked by Digital Spy in July if he'd be interested in returning to Batman, Gordon-Levitt replied: "I just love that [The Dark Knight Rises] has such a great ending.
"They make a lot of sequels, they call them trilogies sometimes. They're usually not really a trilogy, they're just another sequel. This trilogy is one - it has a beginning, a middle and this is a very satisfying end."
Gangster Squad screenwriter Will Beall is currently writing the script for Justice League. Ben Affleck and The Wachowskis have previously been rumoured for the director's chair.
