“I only want to be a husband and a father,” Hercules says humbly. So we all know what’s gonna happen to the family. Dwayne Johnson stars as the Son of Zeus, out for vengeance against men, beasts and descendants of Hades — who cannot be killed by an ordinary mortal. Based on Radical Comics’ take on the mythical muscle man, the Paramount-MGM actioner co-stars Ian McShane, Rufus Sewell, Joseph Fiennes, Peter Mullan and John Hurt. Brett Ratner directs from a script by Ryan Condal and Evan Spiliotopoulos. Check out the new trailer for Hercules, which invades theaters July 25.
