Connelly struck a jackpot with this movie. He didn't have to learn any lines. Just got to moan and groan and act like a zombie. A new spin on the zombie genre. Zombies are now being domesticated, being kept under control by special electronic collars. What you pretty much have are dogs that are able to perform menial tasks. Every family now has one of these "pets". What I can't understand is why nobody complains about the inevitable stench you would have from having corpses wandering around your house.
