Distinctive actor voices
So, I got this idea after catching a friend watching an episode of The Blacklist, which featured Christopher Lambert in a recurring role. I was able to identify him immediately before even seeing him, just from a few spoken words. He often paces his speech in an unusual way and, coupled with his rather distinct tone, he's pretty easy to pick out when you hear him.
So, the question is basically, which actor/actress do you consider to have a unique voice, or is someone that you can always pick out, without even needing to see them?
