Revealing mistake: When Dr. Menard is driving and discussing the zombie plague with the visitors, the "clean" part of the jeep's windshield (i.e. the path of the windshield wipers) appears to be cut out of the glass (probably to provide a better view of the actors and prevent the camera being reflected on the glass).

Directed by: Lucio Fulci
Starring: Al Cliver, Ian McCulloch, Richard Johnson, Tisa Farrow
Other mistake: In the last shot of the film, the zombies are walking across the bridge to New York City. Below, there are cars on both sides of the bridge driving to and from the island with absolutely no concern for the chaos that is supposedly taking place. I guess the filmmakers couldn't stop traffic for a few minutes to get the shot?
Peter West: What is all this about the dead coming back to life again and... having to be killed a second time? I mean, what the hell's going on here?
More questions & answers from Zombi 2
Chosen answer: After the original zombie extra fell ill, the shark handler was made up to play the underwater zombie. The shark was tame, or at least enough to not attack the handler. The makeup would have been latex/oil based, so it would not have been affected by the water. I remember from the commentary that the filming took 1 or 2 days.
