Perfect for Sephiroth from the video game, Final Fantasy VII
For all fans on this board of the classic Playstation RPG...
It didn't hit me right away, but seeing Lee Pace in his makeup, hair, and Elven garb as Thandruil, I saw a resemblance as Sephiroth. Then I thought about it some more and found the resemblance even more uncanny. Even his demeanor as Thandruil is also strangely reminiscent of Sephiroth's character from the game: cold, bitter, taciturn.
If the people at Square-Enix ever come to the decision to make a live-action FFVII film (will not happen in this lifetime), I really can't imagine anyone else in the role. But then again, I'm not up to date on most fan-castings of Final Fantasy characters. The trouble with a film like that is finding castings for the other characters who would be even more troublesome to find a suitable actor for (Cloud Strife, the main character, notably).
