‘Trollhunter’ all good horror-spoofy fun

“Do you think Michael Moore gave up after the first try?” asks a would-be documentarian in “Trollhunter,” a witty “Blair Witch”-style mockumentary about, you guessed it, troll hunting.

Moore, of course, never faced anything quite like this: Three college students decide to investigate some strange occurrences in the Norwegian fjords and end up joining forces with a weary “poacher” named Hans (Otto Jespersen), who’s an undercover troll exterminator employed by a secret government program.

Like a lot of government jobs, troll hunting requires some tedious paperwork (with every kill, Hans must fill out a Slayed Troll Form) and burnout.

“Fairy tales don’t usually match reality,” Hans grunts.

Writer/director Andre Ovredal gives it all a familiar frame: At the beginning, we’re told that what we’re about to see is footage dropped off at a news agency, shot by people who were never seen again.

But “Trollhunter,” despite its herky-jerky camerawork, has much more style than the gritty “Blair Witch.” Those fog-draped fjords provide a distractingly pretty backdrop to this tale of mysterious, massive creatures who roam the forest by night, searching for Christians on whom to munch.

It’s all good horror-spoofy fun – right down to the Polish bear deliveryman (don’t ask) and the repellent “troll stench” in which the students must coat themselves – and ends abruptly before it runs out of steam.

Or troll gas. Don’t ask.
