George Clooney's friends across Hollywood came out to support him on Thursday night for the opening night of his play, "Good Night, and Good Luck."

Dr. Doug Ross, nurse Carol Hathaway and Dr. Mark Greene were back together again — this time, miles away from Cook County General Hospital

After the show last night, Clooney’s celebrity friends and loved ones stayed around for an after-party. Of course, it was the starriest of affairs, bringing in big industry names including Cindy Crawford and Rande Gerber, Hugh Jackman (who starred in his own Broadway revival a couple years ago), Uma Thurman, and Jennifer Lopez.
