Aidan Quinn is set to co-star opposite Jonny Lee Miller and Lucy Liu in CBS’ drama pilot Elementary. The project, written by Robert Doherty, is set in present day and stars Miller as eccentric Brit Sherlock Holmes, a former consultant to Scotland Yard whose addiction problems led him to a rehab center in New York City. Just out of rehab, Holmes now lives in Brooklyn with “sober companion” Joan Watson (Liu) while consulting for the NYPD. Quinn will play NYPD Captain Gregson who worked with Sherlock at Scotland Yard after 9/11 and was so impressed with his work that he has invited him to work as a consultant to the police in New York City. Gregson grew accustomed to Sherlock’s “eccentricities” in the U.K., but knows they won’t necessarily fly in the Big Apple. Michael Cuesta is directing the pilot, produced by CBS TV Studios and Timberman/Beverly. Quinn most recently played an NYPD detective on another primetime drama, NBC’s Prime Suspect.
