New rumors point to Dwayne Johnson as the next Green Lantern.

In a rediscovered Instagram post praising his trainer, the actor included an interesting hashtag, which (un-mashed) reads: John Stewart Can Still Whup Superman’s (butt.) Stewart is, of course, the architect and former Marine who dons the Green Lantern suit after Hal Jordan moves on.

In response to a tweet from IGN, Johnson denied any deeper meaning or hidden revelation in the post. “All I said was… #LanternCanWhupSuperman,” he wrote. But this was neither a confirmation nor a denial, so the question remains. He did, however, confirm that he has been in talks with Warner Bros. to appear in one of their forthcoming films.

Even if Johnson is Green Lantern, it doesn’t mean he will appear in the Man of Steel sequel. Rumors suggest the studio will shoot the movie back-to-back with the official Justice League film, in which John Stewart is more likely to appear.

Denzel Washington has also been rumored for the role. But with WB’s desire to appeal to a younger audience, Johnson could have a slight edge over the veteran actor. Either way, it’s clear WB has no interest in recruiting Ryan Reynolds for a second go. The 2011 film featuring Reynolds brought in more than $200 million at the box office but was panned by critics.

Batman vs. Superman is slated to reach theaters May 6, 2016. Catch The Rock ahead of that in WB’s natural disaster flick, San Andreas, which will premiere June 5, 2015 in 2D and 3D.
