My friend sent me this one.
It is a secret photo which could only been seen in NZ. It is belonged to the riding stunt of Aragorn who is also running a horse training field(don't know how to say that in English) near Wellington. I have seen this picture in their gallery while visiting there in Dec. 2003, but it was not allowed to take pictures then.
BTW, the horse of the Ring Wraith that first showed up in FOTR was extremely cute.
EDITED: I forgot to say that the one who dressed-up like Aragorn wan't Viggo, he is the stunt guy.
