Of course, getting George Clooney to come back would be a dream come true for ER producers, but they are trying to bring back old favorites for the final season (probably) of the hit NBC drama.

So far, only Noah Wyle has officially signed to come back to the show. He'll be on for several episodes, and in the ER not Africa (thank God). But producers have also talked to Julianna Marguiles and Gloria Reuben about coming back, and would love to also grab Eriq LaSalle, William H. Macy, and Laura Innes.
