When LOtR was first shown, I fell for Aragorn immediately. It must be that charismatic look that he has.
Viggo is very much suited for the role of Aragorn (IMO) and I'm glad that he was picked to play the part.
My sister gave me something of his that I'll always treasure. She lives in Wellington, New Zealand and sometime end of last year, I think, they had a book review of Viggo's. She bought his book, Coincidence of Memory, and had him autographed it for me (in my name) ! And she gave it to me when I visited her this year. That was the best post-Christmas gift I've ever had.
Although, I'm not really an art person, his poems and photographs are really quite good.
I've seen some of his other movies. His looks are versatile that he's not that recognisable in each and every one of them.
