John McCall Shoots Wild Bill from Behind

Deadwood is an American Western drama television series created, produced and largely written by David Milch. The series aired on the premium cable network HBO from March 21, 2004, to August 27, 2006, spanning three 12-episode seasons. The show is set in the 1870s in Deadwood, South Dakota, before and after the area's annexation by the Dakota Territory. The series charts Deadwood's growth from camp to town, incorporating themes ranging from the formation of communities to western capitalism. The show features a large ensemble cast, and many historical figures appear as characters on the show—such as Seth Bullock, Al Swearengen, Wild Bill Hickok, Sol Star, Calamity Jane, Wyatt Earp, E. B. Farnum, Charlie Utter and George Hearst. The plot lines involving these characters include historical truths as well as substantial fictional elements. Milch used actual diaries and newspapers from 1870s Deadwood residents as reference points for characters, events, and the look and feel of the show. Some of the characters are fully fictional, although they may have been based on actual persons. Deadwood received wide critical acclaim, particularly for Milch's writing and Ian McShane's co-lead performance. It also won eight Emmy Awards (in 28 nominations) and one Golden Globe.

There were initial plans to conclude the series with two special TV movies, but the plans have not come to fruition. Several of the stars have since commented that the series is now unlikely to return. HBO had repeatedly asserted that the two movies could still be made, but it noted in July 2008 that the possibility of the two TV movies being made was very slim.

The show was produced by Red Board Productions and Roscoe Productions in association with HBO and Paramount Television (CBS Paramount Television in season 3).
