Actor Noah Wyle was meeting and greeting some of the real-life workers who inspire his Emmy-winning tv show. Wyle, star of the series “The Pitt”, visited UPMC Children’s Hospital yesterday. He and co-star, Patrick Bell, talked with the hospital’s emergency department and toured other sections of the facility. A second season of the show is in production right now, with some of the shooting being done in Western Pennsylvania. The program airs on HBO.
