Scrubs is an American comedy-drama television series created in 2001 by Bill Lawrence and produced by ABC Studios. The show follows the lives of several employees of the fictional Sacred Heart, a teaching hospital. It features fast-paced screenplay, slapstick, and surreal vignettes presented mostly as the daydreams of the central character, Dr. John "J.D." Dorian, who is played by Zach Braff. The ninth season saw the transition from Braff as the central character to Kerry Bishé, who plays Lucy Bennett. The show's title is a play on surgical scrubs and a term for a low-ranking or insignificant person (at the beginning of the show, most of the main characters were medical interns, one of the lowest ranks in the medical hierarchy).
Alongside Braff, the first eight seasons of the show feature Sarah Chalke, Donald Faison, Neil Flynn, Ken Jenkins, John C. McGinley and Judy Reyes in starring roles. In the ninth season, only Braff, Faison and McGinley are listed as regular cast members, while the rest, with the exception of Reyes, have made guest appearances. Braff appeared in six episodes of the ninth season before departing. The ninth season also sees many new cast members introduced and shifts the show's setting from a hospital to a medical school. Kerry Bishé, Eliza Coupe, Dave Franco and Michael Mosley became series regulars, with Bishé becoming the show's new narrator.
A complete script is written for each episode of Scrubs; however, actors are given opportunities to improvise their lines during the shooting process. The series has repeatedly featured guest appearances by film actors not generally seen on episodic television, such as Colin Farrell, Heather Graham, and Brendan Fraser.
