Although its numerical title seems to indicate that this is yet another sequel to Lucio Fulci's ZOMBIE (itself often listed as ZOMBI 2 to capitalize on the success of DAWN OF THE DEAD, which was also known as ZOMBI) and ZOMBIE 3, ZOMBIE 4 is actually a (what else?) zombie movie originally known as AFTER DEATH that was renamed to link to its supposed precursors. Set on a verdant tropical island where, 20 years before, a voodoo priest turned all of its inhabitants into the living dead, ZOMBIE 4 finds the only non-zombie descendent of the island returning to her homeland with a band of beer guzzling mercenaries. Soon, the mercenaries find themselves face to face with some rather energetic and hungry zombies while, across the island, a team of scientists unwittingly create even more of the flesh eating corpses. Much in the same vein as ZOMBI 3, ZOMBIE 4 is filled with gore, gratuitous nudity, and just as many laughs as shocks, making it another in a long line of entertaining Italian zombie films.
