George Clooney, this week’s Variety cover subject, wears so many different hats, it’s hard to keep track. He’s won Oscars for producing (“Argo”) and acting (“Syriana”) and critical acclaim for directing (“Good Night, and Good Luck”) and screenwriting (“The Ides of March”).

When he’s not working on a movie, he’s trying to help save the world—as a human rights advocate on the genocide in Darfur. Is there anything George can’t do?

Yes, it’s called Twitter.

Clooney, who has written all his scripts by hand, said he’ll never join the social networking platform. “Just because, I like to have a drink at night,” Clooney told Variety during a lengthy interview at his Studio City home. “I could easily say something stupid, and I also don’t think you need to be that available. I don’t see Matt [Damon] or Brad [Pitt] or myself wanting to get our thoughts out in a 140-character-thing at 3 in the morning.”

And he envisioned a hypothetical bad outcome. “God forbid,” he said, “you take a sleeping pill and wake up and the sentences don’t even make sense. What a horrible idea.”

Clooney’s new film, “The Monuments Men,” which he starred in, co-wrote and directed, opens on Friday. For more about the project, read our profile on Clooney.
