Impostor (2001)

Originally a 30 minute portion for an anthology film, Impostor was retooled into a full length feature film. Based on the Philip K. Dick short story of the same name, it follows the lead character Spencer Olham's quest to regain his identity after being suspected as an alien android, in an future Earth at war with aliens that use the androids as bombs to destroy their enemies homeworlds.

This long-delayed science fiction thriller from director Gary Fleder was actually filmed prior to his box-office hit Don't Say a Word (2001), which preceded it in theaters by several months. Based on a 1953 short story by Philip K. Dick, the film shares that schizophrenic author's long-running obsessions with concealed identity and humanity's potential inferiority to alternative life forms. Gary Sinise stars as Spencer John Olham, a respected government scientist in the year 2079 trying to devise a secret weapon that will help his fellow humans win a decade-long war with invading aliens that are cloning human subjects and using the replicas as walking time bombs. Suddenly, Olham is accused of being an alien spy and a nationwide manhunt to capture him ensues. With even his doctor wife (Madeleine Stowe) unsure that she can trust him, Olham must uncover the truth on his own, even as he's relentlessly pursued by Hathaway (Vincent D'Onofrio), a federal agent charged with destroying the clones. Imposter has a complicated history, originally produced in early 2000 as a 30-minute short to be included in an anthology entitled "The Light Years Trilogy," a project that never got off the ground. So impressed was Dimension Films with the completed piece, however, that the footage was incorporated into a new feature version.
