CinemaCon 2015 - Warner Bros. Pictures Invites You To 'The Big Picture,' An Exclusive Presentation Highlighting The Summer Of 20Why is Superman currently training to out-muscle Green Lantern? Henry Cavill knows he has DC fans talking after his cryptic new Instagram post.

Superman was left in a bad way at the end of "Batman v Superman: Dawn of Justice," and Cavill has not been on the promotion circuit for "Justice League." But he is in training, rehabilitating his knee after an injury, and he got the DC Extended Universe buzzing after this post:

"Wait whaaat?" is right.

Maybe he's just joking about the rumor that his "The Man from U.N.C.L.E." co-star Armie Hammer will play Green Lantern, since there's been speculation that Hammer is up for the part in "Green Lantern Corps." Maybe he's semi-spoiling that the rumor is true? Ryan Reynolds played Hal Jordan in the 2011 movie "Green Lantern," but he is now busy as Deadpool, so it seems more likely that someone new will put on the suit.

Hammer is recovering from a recent surgery, but at SXSW Screen Rant asked him if he's still in the running for "Green Lantern Corps." Hammer shrugged and said, "I don't know. Technically (I am), because they haven't hired anyone."

As ScreenRant noted, Green Lantern is expected to show up in the DCEU at some point, and there are rumors that he might even appear in "Justice League" before "Green Lantern Corps." CinemaBlend joined the speculation brigade after Cavill's tease: "Does that mean we may actually get a Lantern appearance in 'Justice League' after all? Or maybe Green Lantern will be appearing in 'Man of Steel 2' which appears to have recently found a director? Is Cavill expecting to appear in 'Green Lantern Corps'?" Or is Cavill just messing with us?

For now, we just know "Justice League" is opening November 17.
