The screenplay for Urban Decay was written by Don Adams and Harry James Picardi. The movie stars (listed order corresponds to poster order) Dean Cain, Brooke Burns, Chris Williams, Ryan Francis, Tim Thomerson, and Meat Loaf.
Here's a synopsis for Urban Decay from the MySpace official page for the movie: "Cab driver Stan slams into a homeless man, who gets up and walks away, leaving behind a scarf covered with writhing maggots.
Obsessed with the mystery, Stan hunts the ragtag figure through the city, discovering a trail of mangled, half-eaten victims, and an urban legend: Pusshead was a sewer worker who came back from an uncharted tunnel changed into something both living and dead. Parents warn their children that the shuffling zombie will get them if they stay out on the streets too late...
But as the body count rises, Stan finds that the legend is alive and well... hungry."
