Invasion Of The Body Snatchers

Alien spores drift to Earth in “Invasion of the Body Snatchers,” sprouting eerie pink flowers that birth unsettling human replicas using plaster and rubber molds. Leonard Nimoy plays psychiatrist David Kibner. Though the director envisioned a darker finale, the studio opted for a slightly more hopeful conclusion instead.
