Talk about a heart attack. In the screen adaptation of sci-fi guru Philip K. Dick's short story, Gary Sinise plays a future-world scientist who is suspected of being the enemy's latest weapon in an ongoing war with aliens--a clone of himself with a bomb installed in his heart. Hook is, even Sinise doesn't know if he's the real deal or just an Impostor.
Whereas Dick's other works have made it to the screen with far greater poetic flair--the impeccable Blade Runner and worthy Total Recall--this one looks cheaply made (i.e., the futurescape will give you Gattaca and Demolition Man flashbacks). There are some engaging cat-and-mouse conflicts (think The Fugitive: 2079), but the film usually falls for every action-adventure cliché in the universe. Sinise has plenty of, um, heart and gives a performance that is beyond the film. Too bad he's left carrying such a bomb.
