Two years ago, the Toronto film festival’s Midnight Madness program hosted an oddly effective Irish horror effort called “Isolation“, about a mutant cow running amok on a remote farm.

And I thought: Sure, that could happen.

I wasn’t alone. Last year’s festival featured a different breed of mutant movie: “Black Sheep“, the product of a bunch of Kiwis drunk on some combination of Aardman-inspired hallucinations and Peter Jackson’s earlier, funny films.

Well, brace yourselves: It’s secured a theatrical release. And the trailer’s really quite inspired, making it look like a combination of “The Killer Shrews” and the “Dawn of the Dead” remake.

Which, come to think of it, it kind of is.
