After years of talk and bubbling hype levels, HBO has pulled the trigger in its Mexican stand-off and actually made that Deadwood movie. We’ve got the brand new trailer and the release date details right here.

The official HBO synopsis tells us that, “In the Deadwood film, the indelible characters of the series are reunited after ten years to celebrate South Dakota’s statehood. Former rivalries are reignited, alliances are tested and old wounds are reopened, as all are left to navigate the inevitable changes that modernity and time have wrought.”
