I was too lazy to list my top 100. Not so: Michele, Sheila, or Robb. While you're at it check out Michele's list of overrated movies.
Also, via Robert Llama, The All-Time Top 100 Voices in Movies. I would add only that I went to see Phone Booth just to hear Kiefer Sutherland talk on the phone; and I think Sarah Jessica Parker has a nice voice.
And, via Sheila, 100 Funniest Performances Ever, part I.
Feel free to jump in with your own thoughts and opinions.
