HBO has released a short trailer for Deadwood: The Movie. The feature length film is set to premiere state-side on Friday May 31st at at 8/7c. While Sky Atlantic does hold the UK rights, they have yet to set a premiere date. 
More than a decade after the series was cancelled and the notion of wrapping the show with a pair of movies was floated, HBO today announced that production is now underway on the Deadwood movie. The premium cable network said that the movie will continue the story of the HBO original series that produced 36 episodes between 2004 and 2006. Filming is taking place in Los Angeles ahead of a 2019 premiere. 
HBO is (once again) actively considering a two-hour Deadwood TV movie to wrap up storylines left lingering by the abrupt end of the show, it has emerged. Word of this new development first emerged on social media, when original cast member Garret Dillahunt revealed he had heard rumours that the network was looking at greenlighting a movie. In response to that HBO issued the following statement: "In reference to Garret Dillahunt’s tweet regarding the rumored Deadwood movie, there have only been very preliminary conversations".
