ARNOLD SCHWARZENNEGGER and SYLVESTER STALLONE are set to battle it out in the war of film's two toughest guys.

The action heroes agreed to go up against each other in the ultimate blockbuster - but only after deciding who will play the bad guy.

Arnie says, "The obvious problem was who was going to play the hero of the movie - and I'm happy to announce that Sly and I have both agreed it should be me." (NFA/WNTST/PDD)
