Dwayne Johnson has shown off a lot of behind-the-scenes photos by way of his Twitter account. Since he began filming Brett Ratner's adaptation of the Radical comic book Hercules: The Thracian Wars, he's tweeted pictures of everything from sun-soaked helmets to massive sets. Now he's shining a light on Ratner as he figures out a shot on the set.

Johnson wrote: "A 300 BC Demigod. A director @BrettRatner hungry to deliver an epic story. Excited to bring you #HERCULESMovie"

Everyone knows the legend of Hercules and his twelve labors. Our story begins after the labors, and after the legend…

Haunted by a sin from his past, Hercules has become a mercenary. Along with five faithful companions, he travels ancient Greece selling his services for gold and using his legendary reputation to intimidate enemies. But when the benevolent ruler of Thrace and his daughter seek Hercules’ help to defeat a savage and terrifying warlord, Hercules finds that in order for good to triumph and justice to prevail… he must again become the hero he once was… he must embrace his own myth… he must be Hercules.

Johnson stars alongside Ian McShane (Deadwood), Rufus Sewell (Abraham Lincoln: Vampire Hunter), Joseph Fiennes (Flashforward) and John Hurt (V for Vendetta). Hercules opens July 25, 2014.
