Movie hunks Kellan Lutz and Dwayne Johnson are to go head-to-head at the box office in rival Hercules films.

Directors Renny Harlin and Brett Ratner will take charge of the two projects about the powerful Greek demi-god with the former's 3D film, starring Lutz, leading the charge for spring 2014.

Announcing the casting news, Harlin tells The Hollywood Reporter, "It takes more than a good physique to portray the most legendary, mythological personality in history - and Kellan has exactly that, personality. He's not afraid to explore the strengths and vulnerabilities of the character, and he impressed me with his passion and heart."

It's not the first time the Twilight star has been cast as a god - he portrayed Poseidon in Immortals.
