Missed a few because of spelling, - McConaughey, Bardem, McKellen. I think this is a great list. I also think Sir John Gielgud should be on the list - he did Shakespeare and won three Tony awards for stage performances, a Grammy for Ages of Man, an Emmy for Summer's Lease, and then won an Oscar for playing the butler in the movie, Arthur. Somehow someone like Hugh Jackman just doesn't hold a candle to him IMO.
I feel Ernest Borgnine should be on here, too. His body of work was immense and included an Academy Award for Best Actor and numerous Emmys. Few were as diverse as he was.
