[Mithalwen]

I read an interview with Sir Ian McKellen and they did use two horses for Shadowfax - quite reasonable if your actor is and aged thespian who hadn't ridden before as I recall bareback and reinless would have been a bit of a challenge... "the galloping double" was indeed coinsiderably more fiery. They used a horse and a pony for gandalf's cart scenes for scale but his favourite was the pony who played Bill if I remember rightly.

Actually I was convinced there were 2 Asfaloths ..... one in close ups one in long shots (again understanderble since Liv Tyler was another novice) seems to have different markings if not different breeds...... and in half the shots he is overbent and int he others he has normal head carriage.....
