The BBC are pretty good at nature films. Their wildlife unit based in Bristol has produced loads of classic footage using incredible camera work: birds in flight carrying cameras strapped to their legs; lions mating with lenses stuck to their nuts, and gazelles feasting on grass that is actually a mini camera designed to trace the path of the foodstuff as it travels through the gazelles' stomachs and out their agile asses.

The latest development on a BBC wildlife theme is a wolf hunt filmed from a helicopter 2 miles above ground. Owooooooooooo. Clever stuff innit!
