Zombies move much faster than the lumbering zombies commonly seen in films like these; they bite the throats of their victims, are covered in blood and the remnants of body parts, and are continually being shown getting shot in the head by humans with shotguns. When a newborn baby is born as a zombie (which is not shown), there's the sound of a gunshot to signify that the baby has been killed. A character is impaled in the head with a spike. Another character is stabbed in the eye. Early in the film, when the zombies first start to appear, a panicked character is run over by an ambulance.
While two of the characters are hiding from the zombies in the shopping mall, they pass the time by having sex. At the end of the film, a camcorder shows quick flashes of one of the characters before the zombie attacks, hanging out on his boat with various naked women.
"Motherf---ers." "Faggot." "F--k." "F--king." "S--t." "Tap that s--t."
One of the characters decides to fill the empty hours of waiting and hiding out from the zombies by drinking and smoking cigarettes. This character frequently appears drunk in the film.
