George Clooney gives his real thoughts of former 'ER' costar Noah Wyle's 'The Pitt'

"The Pitt" officially has the Doug Ross seal of approval.

In an appearance on "Late Night with Seth Meyers," George Clooney shared his thoughts on the acclaimed medical drama series from Max, which stars his former "ER" colleague Noah Wyle.

"It's so good," Clooney said of "The Pitt," going on to heap praise on Wyle.

"I have to say, we've been really dear friends since the show, since we did the pilot of the show. He is just the most honorable, talented young man — I get to say, because I'm an old man — and I cannot be happier for his success on the show. The show is just a beautiful show, and he does a great job with it."

Wyle stars as Dr. Michael "Robby" Robinavitch on "The Pitt," a medical drama set in a Pittsburgh hospital's emergency room. Every episode chronicles one hour in the hospital, with the full first season telling the story of one shift. The series was created by former "ER" writer R. Scott Gemmill and is produced by former "ER" producer John Wells.
