Something tells me from looking at this pic that the shooting of this movie is brutally demanding for everyone involved.  Can you imagine having to ride a horse on icy mountain slopes while wearing all that 'Knightly' garb?

I sincerely hope Nic is being careful and at the end of the day is indulging himself in long jacuzzi soaks, massages and warm mugs of Glogg.
