Chicago Med

Shares a universe with other shows created by Dick Wolf: 'Law & Order: Special Victims Unit', 'Chicago Fire', 'Chicago P.D.' and 'Chicago Justice'. This means that sometimes characters of 'Chicago Med' appear on his other shows and its story continues there or vice versa.

Dr. Will Halstead was introduced before the backdoor pilot as the brother of 'Chicago P.D.''s Jay Halstead.

Dr. Natalie Manning's name was originally Lilly before the show aired, as clearly seen on her lab coat in early promotional pictures, but was changed before the pilot episode.
