Rejoice! The long-rumored Deadwood movie is officially happening.

Deadwood fans rejoice! The long-rumored train is finally leaving the station — a Deadwood movie is officially on the way.

At the Television Critics Association summer press tour on Wednesday, HBO programming president Casey Bloys announced that the much-discussed film is at last scheduled to begin production. “It is greenlit,” Bloys said, adding that the movie is tentatively scheduled to begin shooting in October, aiming for a spring 2019 air date.

Deadwood, which premiered in 2004 and ran for three seasons before its cancellation in 2006, has earned plenty of critical acclaim, with Vox’s critic at large Todd VanDerWerff calling it “the best drama ever made.” Created by David Milch, the series was an ensemble drama set in 1870s South Dakota, and followed the growth of a gold-mining camp known as Deadwood into a proper town.

Rumors of a movie have been floating around for some time, picking up steam in the last year as actress Kim Dickens, who played Joanie Stubbs on the show, revealing on VanDerWerff’s podcast that she’d read the script, and her fellow former cast members Robin Weigert and Ian McShane saying that plans were in the works.

Now those rumors are set to become a reality. “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.”
