Wildlife film maker Gordon Buchanan had a close shave with a polar bear, after one spent 40 minutes trying to work out how to crack open the perspex case he was sitting in.

Buchanan managed to film the entire event, which starts with the polar bear curiously sniffing and prodding away at the man box. It all seems harmless enough, and like the two will emerge from the process as best buddies, until things turn rather hairy when the bear starts smashing into the case with all of its body weight once it's found the weakest point of the box.

We think Gordon survived the experience. After all, his plastic man box was designed to survive such attacks. [YouTube via Gizmodo Australia]
