Pod people (also known as The Body Snatchers) is a nickname given to an alien species featured in the 1955 novel "The Body Snatchers" by Jack Finney, the 1956 film "Invasion of the Body Snatchers", the 1978 remake of the same name and the 1993 film "Body Snatchers". Not to be confused with the 2007 film "Invasion of the Pod People" though they share similar themes.
Without The Body Snatchers, there would have been no Invasion of the Pod People
