This is perhaps the best adaptation of Jack Finney's novel, with Donald Sutherland, Brook Adams, Jeff Goldblum and Veronica Cartwright trying to escape from an invaded San Fransisco. The movie starts with alien spores leaving their home planet, landing through the earth's atmosphere and taking root on the native plants. Brook Adams brings one of these strange flower pods home-and soon she notices that her live-in boyfriend is acting much differently, as if he has no emotions. And the small pod is gone. Paranoia builds when Goldblum finds an unformed version of himself at work and when Sutherland tries to make phone calls to the authorities and the operator calls him by name, asking him where he is at. It seems that everyone in San Fransisco is being replaced by emotionless copies of themselves. I like this version best because of the feeling of dread it conveys... the characters do their best to escape but there is no escape. At the end, when the human Cartwright approaches Sutherland, who she thinks has escaped duplication, he stops and accusingly points at her, emitting this horrible noise that the pod people do. She screams and screams. No escape.
