In a scene from his upcoming BBC nature documentary The Polar Bear Family & Me, wildlife filmmaker Gordon Buchanan finds himself staring at the salivating end of a hungry polar bear from inside a lunchbox safebox.

All told, Buchanan was stuck inside for some 40 minutes as the bear desperately licked the Plexiglas hoping to reach the chewy center.

The Polar Bear Family & Me — shot over the course of three seasons in Svalbard, Norway — premieres on BBC Two next Thursday.
