Variety:

HBO is officially moving forward with the “Deadwood" movie. The announcement was made by HBO programming president Casey Bloys at the TCA summer press tour on Wednesday.

“All of these people worked hard to get this together,“ Bloys said. “It’s been a logistics nightmare getting all the cast members’ schedules together, but we are there. It is greenlit.“

Bloys also said the movie is currently scheduled to begin shooting in October for a spring 2019 air date, but added that the date is not “set in stone.“

It’s a bummer that this will be an HBO movie, not a proper theatrical release, but I for one cannot wait to return to the world of Deadwood!
