[Video/Documentary] Failed expedition to the south pole.

I remember seeing a documentary a few years ago on either bbc or the discovery channel. It was about a expedition to the south pole in the early 20th century. I think it was based on Cpt.Scott's expedition.

I remember images of men in the snow sitting waiting to die in the cold, I think possibly their boat wound up stranded in the ice. Also there was some mention of cannibalism. Again it may not have been based on Scott's expedition, since the party was much larger I think.
