"Batman vs. Superman" cinematographer Larry Fong may have accidentally leaked the return of the Joker.

According to the Man of Steel Fan Page, Fong released an image of a facedown playing card stuck on a wall.  However, the report didn't specify where Fong posted the image.  You can check it out for yourself here.

The "Man of Steel 2" production hasn't confirmed the appearance of the Joker in the series, but Ben Affleck will play Batman, Gal Gadot is the newest Wonder Woman, Jesse Eisenberg is Lex Luthor and Henry Cavill will be reprising his role as Superman.  There have also been rumors of "Game of Thrones" actor Jason Momoa will play Aquaman in the upcoming film.

Momoa recently slammed the rumors when a ComicBook.com reporter asked him about the "Man of Steel" production, according to Yahoo Movies.  Momoa wasn't angry with the reporter, but did explain why he has become frustrated with Aquaman speculation:

"What does everything tell you? No. Stop asking me. It's so annoying. Sorry, you're not annoying.  Oh you're the press? Get the f*** out of here. Here, put this in there - you're a d***, you're a d***. [Allowing the audience to laugh] You're not a d***, I'm just playing. You know what, I think it started when people said 'What superhero would you play?'

"And I'd say Batman and Superman, they'd be awesome together. Then people were like, 'He's in Batman vs. Superman!' I'm like, I really like Lobo. 'HE'S LOBO!!' And then some a**hole was like 'He's Aquaman! And I'm like - what did you just call me? Where the f*** do you pull out Aquaman? Seriously... And then it shows up on the internet. Not that it's a bad rumour."

"Batman vs. Superman" will be released to theaters on May 6, 2016.
