I have no idea why this movie is such underrated. Yes, Gary Fleder is no Steven Spielberg or Ridley Scott. He doesn't have the excellent imagery or visual wonders of the other directors' films. But at the same time, he has been more faithful to the original short story than Scott or Spielberg could have been. He has added only one major twist which made the film rather more interesting. And one major credit of the film is that it could capture quite obviously the feel of paranoia that's been the mainstay of Philip Dick's most stories.

Gary Sinise is always pleasure to watch on screen. And in this case his performance is flawless. D'Onofrio plays the tough security officer with enough passion. Madeline Stowe is rather frigid in her role.

In short, 'Impostor' is a gripping tale with solid plot and enough substance. A must see for every genre fan, regardless of the fact that one of the greatest sci-fi writer has penned the story.
