This one looks like it could either work well or just miss the mark - it's another zombie comedy (zom-com if you prefer) which features domesticated zombies which at some point go wild.
This picks up nicely from the idea touched on at the end of Shaun of the Dead and interestingly comes back to the origins of zombie mythology, which is zombies as slaves. (In Haiti, it wasn't zombies per se that the locals were afraid of - as the whole flesh eating thing isn't part of zombie lore there - but of actually becoming a zombie and having to keep working beyond death)
Best of all though, it stars the guy who played the paedophile dad in Happiness
