With NBC is in the final stages of renewing the medical drama "ER" for its fifteenth and final season, producers of the show reportedly are looking forward to bring back its original cast members in a bid to give the series a proper send-off. And among the stars the producers want include George Clooney and Julianna Margulies.

"We want to revisit characters that have existed on the show over the years and say where they are now," producer David Zabel said in a statement. "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."

According to Entertainment Weekly, Zabel and producer John Wells have said they would like to see an update of Clooney's character Doug Ross and also Margulies' character Nurse Carol Hathaway. In addition to both stars, Noah Wyle reportedly already agreed to reprise his role as Dr. John Carter for four episodes.

Goran Visnjic and Maura Tierney are the two other stars expected to make a return to "ER" for its final season. Greater than all, the producers would even like to bring back Anthony Edwards despite the fact that his character died on the show.

"The toughest will be getting Tony Edwards because his character is dead," said Zabel, adding "That's a little tricky, but there are ways to do it that we've thought about. Even if it were like a lost episode from 1996 featuring him and Wyle."

No words from both Clooney and Margulies just yet about the plan.

Clooney, despite his big screen success, gained fame as one of the lead doctors in the long-running television drama, "ER" (1994-1999), as Dr. Douglas "Doug" Ross. He quit the show in order to focus on his movie career, a move that seems to have worked out well for him.
