CHICAGO, Jan. 30 (UPI) -- Cast and crew members of the Chicago-set television series "ER" are filming the shows last exterior scenes in the Windy City.
The series, which is shot mainly in Los Angeles, is set to wrap after 15 seasons with a finale airing April 2.
The Southtown Star newspaper said some of the actors, as well as many of the show's behind-the-scenes workers, descended on Chicago Thursday to film the series' final outdoor scenes.
"I think I've seen about every corner of this city," actor Noah Wyle told the newspaper.
Wyle played Dr. John Carter on the medical drama from 1994 to 2006, and has returned this season for a last few appearances on the show as it wraps up.
"I'm really grateful for the way this city has supported and entrusted us," Wyle added. "I'm sorry it's all coming to a close."
