Are two Arnold Schwarzeneggers better than one? I started out thinking yes but eventually changed my mind, as the law of diminishing returns kicked in. One Arnold takes over the wife, daughter, house, and life of the other in this fitfully enjoyable but overextended SF thriller about cloning, directed by Roger Spottiswoode from a script by Cormac and Marianne Wibberley. When the dictates of routine action take over, some of the satirical possibilities of the theme that were initially tapped are forgotten. Insofar as this is distinguishable from others of its ilk, it's a far cry from Total Recall, but vastly superior to End of Days; insofar as it isn't, it's a clone itself. With Tony Goldwyn, Michael Rapaport, Michael Rooker, Sarah Wynter, Wendy Crewson, and Robert Duvall. 124 min.
