Invasion of the Body Snatchers

"Invasion of the Body Snatchers" stars Donald Sutherland and Brooke Adams as friends, Matthew and Elizabeth, who work at the Health Department in San Francisco. They increasingly suspect that people are somehow being duplicated and trace the problem to alien plant pods. Leonard Nimoy plays Matthew’s pop psychologist friend while Jeff Goldblum & Veronica Cartwright are on hand as a couple who run a mudbath parlour. The film follows their investigation into the mysterious duplicates, which lead them to discover an amorphous parasitic alien race that abandons its dying planet and travels across space, eventually coming to Earth.
