Oz was an American crime series created by Tom Fontana for HBO. It ran from July 12, 1997 to February 23, 2003 for six seasons.
The series follows the lives - and, frequently, deaths - of prisoners incarcerated in the Oswald State Correctional Facility, particularly those in 'Emerald City', an experimental block that mixes a carefully chosen number of prisoners from various gangs and groups (including neo-Nazis and black gangs) in the hopes of reducing tension between them. Central characters include wheelchair-bound former drug dealer Augustus Hill (Harold Perrineau Jr.), who also acts as the show's Greek chorus during surreal, out-of-continuity scenes; warden Leo Glynn (Ernie Hudson); former lawyer Tobias Beecher (Lee Tergesen) and neo-Nazi leader Vernon Schillinger (JK Hudson).
