From Hong Kong's king of action, John Woo, comes a high-tech adventure which has maximum visual thrills and zero credibility, but is none the worse for it. Good guy John Travolta demonstrates his loyalty to the F.B.I in spectacular style by having the face of psycho killer Nicolas Cage transplanted on to his own, in order to save L.A from a huge Special Effect. Cage, meanwhile, in characteristically maniacal mode, has decided to add to the confusion by pilfering Travolta's endearingly twinkly features for himself. All highly implausible but hugely entertaining.
