I've seen a few documentaries about wolverines; this is definitely one of the best. It follows the travails of a female wolverine in Scandinavia as she attempts to find food and raise cubs over a brutal winter. Some of the more improbable beliefs about the animal are dispelled (like the old bromide that bears are afraid of them); however, the oft-repeated claim that a wolverine can kill a deer many times its size is, shockingly, confirmed. On camera, no less.
