Although the report doesn't state what role Rocky would play, it's almost certainly has to be the Greek god, right? (Could you even imagine a "Hercules" movie starring the Rock where he played someone other than Hercules?)
The movie is being adapted from the 2008 graphic novel "Hercules: The Thracian War."
Johnson, who's currently starring in "Journey 2: The Mysterious Island," obviously won't need to do much preparation for the role. (Get it? It's because he's already very muscular -- like Hercules!) Of course, whether he has time remains to be seen: in addition to press rounds for "G.I. Joe: Retaliation" (out this summer), Johnson is starring in Michael Bay's "Pain and Gain" as well as the eventual sequel to "Fast Five." It's a schedule that even he admitted was tight.
"Unfortunately, we have a very small window of time to shoot ['Pain and Gain'] before I go off and film 'Fast Six,'" he recently told Moviefone.
"Hercules" would be Ratner's first film since "Tower Heist."
UPDATE: According to Variety, Johnson has signed on star in Brett Ratner's "Hercules." Production will start this October.
