Casting Voldy in GoF

[Dean]

Up until now at least Voldemort plays a very minor role in the story;
he only appears once (I think) in each of GOF and OotP. These scenes 
are short spiteful exchanges and action scenes that should be easy to 
act out  (I would say ARE easy to act but then I think back to who 
ever played Quirrell in PS, if the actor who plays Voldie is that bad 
I might never recover) 
Anyway my point is the actor will be chosen for what ever look the 
director thinks Voldie has and maybe not so much talent.
Did I confuse you?  I think I confused myself.
