Everyone keeps saying that Ralph fiennes, is too good looking for the part of voldemort. Well I've got two points that say it doesn't matter what he looks like:
1 the young Voldemort was good looking
2He only appears to the audience as anything other than a voice at the end. Where he is described as bone thin, with long arms and fingers and red slits for eyes. It is very likely he will be completely computer animated, so Ralph will only have to lend his voice to the role.
