In the following menu screen, highlight one of the bottom two trailers on the screen and then press the [Left] arrow key on your remote control. This will highlight a skull. Now, press [Enter] and you will get to see a trailer for Lucio Fulci's original schocker "Zombie". It is the international trailer and therefore advertises the film as "Zombie 2".
