Susan Surandon to appear with George Clooney on "ER" episode!

Is she going to play his Mom?...........
How do you get Susan Sarandon to appear on ER? Easy. Let her work with George Clooney.
Sources tell me exclusively that Sarandon filmed scenes late last week with fellow Oscar winner Clooney on the set of ER at Warner Bros. Studios in Burbank. The episode will air toward the end of the current final season of the long-running NBC hit.
So what went down on set? And which other stars got to share screen time with Dr. Doug Ross, aka Clooney?
According to sources who were there on set for Clooney's return, ER series regular Linda Cardellini (Sam) also got the chance to work with Clooney in at least one scene. So far no details of the storyline have been revealed.
"He was charming," one ER crew member tells me. "Everyone had a great time with George, and he told some great stories about the old days. He really enjoyed himself and was glad he did it."
Sarandon's last NBC guest spot was in 2001 on Friends (a show on which Clooney appeared in 1995). Both actors have received attention recently for being part of the more than 2,000 actors who have declared opposition to a Screen Actors Guild strike.
