This atmospheric and stunning shot is a frame from Lucio Fulci’s classic grindhouse horror Zombi 2, aka Zombie Flesh Eaters that was released in 1979.
It shows the bloated, fat zombie that is seen on the boat at the start of the movie who proceeds to attack the police that board the boat, emerging from the cold waters in New York. It is assumed that this zombie has drifted in the boat to the USA from the island Matool, which is the focal point of the zombie outbreak in the movie.
The frame below was never actually used in the final cut of the film, so one can only suppose that it was originally filmed to help explain how the outbreak spreads through the city. The shot was however used in various lobby cards and production stills that were used to advertise the movie.
