This stars new action hero The Rock on a mission to save Seann William Scott from a rumble in the Brazilian jungle. Rock seems quite a nice chap, really, very sincere, speaking in surprisingly sensible, joined-up sentences. He is, mind you, as big as an Alp and makes Arnold Schwarzenegger - who appears in the opening scene, walking out of a disco, like Elvis leaving the building - look like a mere slip of a thing.
