Elementary is an American procedural drama series that presents a contemporary update of Sir Arthur Conan Doyle's character Sherlock Holmes. It was created by Robert Doherty and stars Jonny Lee Miller as Sherlock Holmes and Lucy Liu as Dr. Joan Watson. The series premiered on CBS on September 27, 2012. It is set and filmed primarily in New York City. With 24 episodes per season, by the end of season two Jonny Lee Miller became the actor who had portrayed Sherlock Holmes the most in television and/or film.
The show follows Holmes, a recovering drug addict and former consultant to Scotland Yard, as he assists the New York City Police Department in solving crimes. His indifference to police procedure often leads to conflict with Captain Thomas Gregson (Aidan Quinn), although the two still remain respectful of one another. Holmes is accompanied by Dr. Joan Watson (Lucy Liu), who initially acts as his sober companion. She is a former surgeon and was hired by Sherlock's father to help him in his rehabilitation. They eventually begin to work together on his cases, and she becomes Holmes' apprentice and then partner. The series also features Holmes' ongoing conflict with his nemesis Jamie Moriarty (Natalie Dormer). Other supporting roles include Jon Michael Hill as Detective Marcus Bell, Rhys Ifans as Sherlock's brother, Mycroft Holmes, and John Noble as Sherlock's father, Morland Holmes.
