The Hollywood toughguy has previously spoken out against excessively gory films, but his newest blockbuster - about a team of mercenaries attempting to overthrow a South American dictator - contains a string of bloody scenes.
But Stallone has assured fans the only characters who are hurt in The Expendables are those who mistreat others.
He says, "The one thing in my films... I only kill people that need to be killed. Let me put it this way, the ones that deserve it get it and they get it good and the ones that go after women really get it, you know what I mean? Really get it."
