For over 60 years, Sir David Attenborough has captivated audiences with his documentaries, covering all manner of flora and fauna. Now, the world's foremost wildlife broadcaster has turned his attentions to a new subject: curling. The Winter Olympics' most bizarre sport is the subject of a playful new video produced by the BBC. "In all my years of exploration, these are the creatures I find most curious," says Attenborough, whose credits include the Life documentary series and Planet Earth (his narration is often replaced for US audiences). If only all Olympic commentary was this engaging.
