ER Bringing Back Clooney with Margulies before Checking Out
by Matt Mitovich
The on-screen reunion that many felt needed to happen before ER could
properly end its 15-year-run will come to fruition after all.
Though neither NBC nor Warner Bros. have yet to officially confirm the
news, sources tell TVGuide.com that both George Clooney and Julianna
Margulies — aka one of the medical drama's premiere on-screen couples,
Dr. Doug Ross and Carol Hathaway — will resurface in one episode
before County General shutters its doors on April 2. Both actors are
reportedly filming their scenes this week, on a closed set.
Clooney last checked into ER in May 2000, making an unbilled, end-of-
episode appearance so as to properly usher off Margulies' nurse
Hathaway. The secretly filmed scene had Carol approaching a dock,
where Doug waited for her, smiling yet silent.
Just last week at the TCA Winter Press Tour, TVGuide.com asked NBC
entertainment president Angela Bromstad if the extension of ER's final
run by three episodes might afford John Wells additional time to talk
Clooney into an encore. Her response: "Ask John Wells." Days later,
the ER boss actually dismissed the idea, saying that Clooney — whose
film career has soared over the past decade — is "too busy."
Indeed, Clooney's publicist as recently as September pulled a Debbie
Downer by deflating talk of the movie star's possible drop-by, saying,
"It is something he has already done."
Weeks later, Margulies herself scoffed at the idea of returning during
ER's final season, explaining, "I left Carol Hathaway in the best
scenario possible. I can't imagine making it any better."
Already this season, Anthony Edwards reprised his role as Mark Greene
(appearing in a "new" flashback with fellow original cast member Laura
Innes aka Weaver); Alex Kingston put in an appearance as Mark's widow,
Elizabeth, on Jan. 15; and Noah Wyle is due back as Carter for the
final four episodes.
