Invasion of the body snatchers (advance)

The first remake of the paranoid infiltration classic moves the setting for the invasion from a small town to the city of San Fransisco and starts as Matthew Bennell notices that several of his friends are complaining that their close relatives are in some way different. As the invaders increase in number they become more open but who can he trust to help him and who has already been snatched? This is an advance poster from the film's first release, folded as originally issued to cinemas.
