Stoic Carol was a fan favorite for six seasons before Margulies moved on to other projects, including The Good Wife. Next up, she’ll star in National Geographic’s six-part adaptation of The Hot Zone (premieres May 27) as Nancy Jaax, a U.S. Army scientist who takes drastic measures to help prevent an outbreak of the Ebola virus.

George Clooney (Dr. Doug Ross)
ER‘s resident dreamboat, pediatrician Doug Ross, checked out during Season 5 (he came back for a cameo in Margulies’s last episode). Clooney returns to the small screen to produce, direct and costar in Hulu’s limited series Catch-22 — he plays Lt. Scheisskopf—a new adaptation of the Joseph Heller novel set during World War II (premieres May 17).
Noah Wyle (Dr. John Carter)
Wyle began his tenure as med student John Carter in the pilot and stuck around for 11 seasons, becoming the show’s longest-running original cast member. Starting April 28, he’ll tackle the role of Daniel Calder, a widower reeling from the violent death of his African-American husband in CBS’s The Red Line, a new drama exploring the nature of family, tragedy and racial bias.
Eriq La Salle (Dr. Peter Benton)
As brilliant as he was mercurial, surgeon Peter Benton spent eight seasons casting his withering gaze across County General. These days, La Salle is peering through the other end of the camera lens; he’s a director and exec producer for Chicago P.D., NBC’s Wednesday-night drama about the Windy City’s elite Intelligence Unit, currently in its sixth season.

Alex Kingston (Dr. Elizabeth Corday)
Salt-of-the-earth British surgeon Elizabeth Corday made regular rounds from Seasons 4 through 11, striking up a romance with Dr. Benton and later marrying Dr. Mark Greene (Anthony Edwards). In Prime Video’s new thriller The Widow, she plays Judith, a sounding board and voice of reason for Kate
Beckinsale’s aggrieved title character.
Maura Tierney (Dr. Abby Lockhart)
Over nine seasons, Abby Lockhart graduated from ob-gyn nurse to ER doc—and got hitched to the hunky Dr. Luka Kovac (Goran Visnjic). In Showtime’s
drama The Affair, which airs its final season later this year, her character hasn’t been so lucky: Helen was cheated on by her first husband, then her second husband got diagnosed with terminal cancer.
It's tough to believe a full decade has gone by sinceER, NBC's groundbreaking medical drama, aired its final episode on April 2, 2009.
For 15 seasons, viewers were swept into the frenetic hallways of Chicago's fictional County General hospital for a realistic gurney's-eye view of doctors and patients in the throes of every imaginable form of physical and emotional trauma. It was gritty, gripping, and a huge hit, spending multiple years the top of the ratings and winning 23 Primetime Emmys.
