I think Peter O'Toole is great, and really he's probably lucky to still be around!
I remember a great appearance he had on Carson or Letterman when he told a story from Lawrence of Arabia. They were shooting closeups for a camel charge, and O'Toole and Omar Sharif were really going to be riding galloping camels. The night before they were talking about how they were going to do it. Sharif said he was planning to fashion some kind of rope rig that basically tied him down to the camel. O'Toole said he wasn't going to do anything like that, he would just get really drunk beforehand. And Sharif said, as if it went without saying, "Oh, I'll be drunk!"
Best of luck to Mr. O'Toole in his retirement.
