Impostor is a 2001 American science fiction psychological thriller film based upon the 1953 short story "Impostor" by Philip K. Dick. The film starred Gary Sinise, Madeleine Stowe, Vincent D'Onofrio, and Mekhi Phifer and was directed by Gary Fleder.
Plot In the year 2039, Earth is attacked by an alien civilization from Alpha Centauri. Force field domes are put in place to protect cities, and a totalitarian global military government is established to effect the war and the survival of humans. The Centaurians have never been physically seen. Thirty years later, Spencer Olham, a designer of top-secret government weapons, is arrested while on his way to work by Major Hathaway of the Earth Security Administration (ESA), being identified as a replicant created by the aliens. The ESA intercepted an alien transmission which cryptanalysts decoded as programming Olham's target to be the Chancellor, whom he was scheduled to meet. Such replicants are perfect biological copies of existing humans, complete with transplanted memories, and do not know they are replicants. Each has a powerful "U-bomb" in their chest in the exact design of a human heart, which can only be detected by dissection or a high-tech medical scan, since it only arms itself and detonates when it gets in close proximity to its target. Detection via the special scan works by comparing against a previous scan, if there was one. Major Hathaway begins interrogating Olham. As Hathaway is about to drill out Olham's chest to find the bomb, Olham breaks loose and escapes, accidentally killing his friend Nelson in the process. With the help of underground stalker Cale, Olham avoids capture and sneaks into the hospital where his wife Maya is an administrator to get the high-tech scan redone and prove he is not a replicant. But the scan is interrupted by security forces before it can deliver the answer. That evening, after fleeing from the city, Olham and Maya are eventually captured by Hathaway's troops in a forest near an alien crash site, close to the spot where they spent a romantic weekend just a week or so before Olham's arrest. Inside the ship they discover the corpse of the real Maya, and Hathaway shoots and kills the replicant Maya before she can detonate. Hathaway thinks he has killed the true impostor, but as his men move debris away from the Centauri ship, the real Spencer Olham's body is revealed as well. At that moment, Olham realizes aloud that both Maya and himself really are alien replicants, and the secondary trigger (his awareness of what he truly is) detonates his U-bomb, destroying himself, Hathaway, his troops, and everything else in a wide area in a fiery nuclear explosion. A news announcement states that Hathaway and the Olhams were killed in an alien enemy attack, implying that the government covered up or are unaware of the truth. Cale wonders if he ever really knew Olham's true identity.

Production The film adaptation was originally planned to be one segment of a three-part science fiction anthology film titled Light Years, but was the only segment filmed before the project fell apart. The other shorts were to be adaptations of Isaac Asimov's story "The Last Question" by Bryan Singer and Donald A. Wollheim's story "Mimic" by Matthew Robbins. "Mimic" had already been adapted into a film of the same name, but with a different script. The short was originally written by Scott Rosenberg, with revisions by Mark Protosevich and Caroline Case. When it was decided to expand the short into a feature-length film, additional scenes were written by Richard Jeffries, Ehren Kruger, and David Twohy. Burn areas in Running Springs, California, were used to create the spacecraft crash site. Sets were constructed in Angeles National Forest and in numerous areas around Los Angeles. Most of the interiors were built on stage in Manhattan Beach, including a two-story hospital and 3-story pharmacy, and a commuter transport station with articulated commuter "bugs". Other filming locations included the Coachella Valley. The movie was made on an estimated $40 million budget.
