Who should play Voldemort in GoF?

[Donna]

I've read, somewhere, that Rowan Atkinson was being considered for 
the role of Voldemort for GoF.  While he was deliciously evil as The 
Blackadder, I cannot see Mr. Bean as evil incarnate in Voldemort.  
Frankly, I would be giggling and waiting for some slapstick moment.  
My personal choice for the role...Brad Dourif.  He has always played 
the most wonderful villains.  Consider his portrayal of Pieter De 
Vries in Dune (the only reason that movie is worth watching).  And 
how about his turn as Grimma Wormtongue in "The Two Towers".
