Despite packing a pretty tremendous supporting cast including Ian McShane, John Hurt and Rufus Sewell, Brett Ratner's 3-D epic Hercules is about only one actor: Dwayne Johnson. The former WWE superstar has proved his clout in the blockbuster box-office game, though Paramount's new big-budget action is almost certainly his biggest test yet.

A second trailer for Hercules rolled out online this week, with the divine hero on the hunt for revenge against the gods who murdered his family. He battles both man and beast, including the multi-headed serpent Hydra and the hellhound Cerberus.

With a script from Ryan J. Condal and Evan Spiliotopoulus and based on the Radical Studios graphic novel, Hercules is likely to be an all-out action romp - though will it go the way of 300, or.the other Hercules?

A rival project, The Legend of Hercules, starring Kellan Lutz in the lead role, bombed at the box-office earlier this year. 

"No one seems to have high hopes for it - though it might well help to pass a wet afternoon when it shows up on Netflix 15 minutes from now," said Mike McCahill of The Guardian.

The trailer suggest that Johnson's Hercules will fare better than The Legend of and it will almost certainly perform at the box-office. The former wrestler's last major movies - Fast & Furious 6, Pain & Gain, Journey 2: The Mysterious Island, Fast Five and The Other Guys - took over £700 million worldwide. 

Paramount Pictures will release Hercules on July 25.
