DVD Verdict: Directed and produced by Peter Fison, and narrated by Eric Meyers, 'NOVA: Extreme Animal Weapons' is one of the most incredible, enthralling hour's that I've spent watching a documentary in years.

The documentary, with incredible close up photography and cinematography, showcases the fact that most every creature on Earth depends on a weapon of some sort to survive. Ergo, 'Extreme Animal Weapons' brings forth imagery of animals with oversized weaponry, whilst at the same time uncovering a bold new theory about what triggers an animal battle in the very first place.
