Gangs of the Dead (2006)

A meterorite falls from outer space, crashes through a bridge, lands on a group of homeless people and turns them into drooling zombies. While the hobo zombies lumber down the street, two gangs meet in a warehouse to conduct some business and the undercover police operation prepares to take them down. Unfortunately on the way to make the bust, the police encounter the zombies and havoc ensues.

The two gangs, two officers, and a weatherman all end up making a stand in the warehouse. Even in times of the earth being overrun by homeless dead, they still can't work together to ensure their own survival.

Those looking for a true zombie film will be disappointed as there is not so much zombie in the film, as there is stupid gang members. Also the zombies have green skin and drool a thick blue liquid, which is just plain strange and not as scary as if they were drooling blood.
