ER is returning for their 15th and final season this fall, and to spice things up, producers are looking to enlist the help of some of their veterans.
Noah Wyle is already set to return as Dr. Carter for four episodes, and Goran Visnjic is expected to pop in as well. Maura Tierney had previously said she'd leave after this season, but it sounds like she'd be around for at least some of this final round. That leaves fans wondering about Eriq LaSalle, Julianna Margulies, and best of all, George Clooney.
The producers tell EW, "We want to revisit characters that have existed on the show over the years and say where they are now. We'd love to get them all back in some way, but that doesn't mean we're going to. But we're gonna try."
