With every passing day, the long-promised Deadwood movie looks less like a fantasy and more like reality.

Robin Weigert, who famously portrayed Calamity Jane in the HBO western, suggested that a Deadwood reunion is closer than ever.

“It’s safe enough to say it’s happening this fall,” Weigert said in an interview. “There’s a set being built and tax incentives to get it done. A lot of (actors) have signed on. There’s a 90 percent chance it’ll finally happen.”

Indeed, the stars seem to finally be aligning for the project, which has been more than 10 years in the making.

After the show’s third season in 2006, it was canceled in a dispute between its studio (Paramount) and network (HBO). At the time, HBO and Deadwood creator and showrunner David Milch agreed to two two-hour TV movies in lieu of a fourth season.

The movies never materialized, but there were enough encouraging comments in the 12 years since then that fans never lost hope that they might get a final chapter to the series.

At the Television Critics Assn. press tour in January, Casey Bloys, president of HBO programming, was optimistic about the prospect of the movie and thought filming could potentially begin this fall.

In April, Deadline reported that a Deadwood movie project had received a nearly $4.2-million California tax incentive, despite not yet receiving an official green light from the network.

HBO had no news to report about a potential Deadwood film after an inquiry on Friday morning. And representatives for David Milch did not immediately respond to a request for comment.
