"Deadwood" is holding a party.

When the acclaimed HBO western returns with a long-anticipated movie this spring, many things will have changed — and many things remain the same.

As star Ian McShane, who plays brothel owner Al Swearengen, has revealed, the town is entering a new phase of its life, though the players are still familiar faces.

They include Al, sheriff Seth Bullock (Timothy Olyphant); wealthy goldmine owner Alma Garrett (Molly Parker); businessman Sol Star (John Hawkes); former prostitute Trixie (Paula Malcomson); and the notorious, greedy, money-grubbing tycoon George Hearst (Gerald McRaney).

"Deadwood is celebrating South Dakota as a state, and Hearst has come back and Alma has come back in town, so you have all the main characters converging and how they changed in 10 years," McShane told reporters at the Television Critics Association press tour, while promoting Starz's second season of "American Gods."

He continued: "Now Hearst wants to put telegraphs in town, which isn’t going too well. Al has had a little bit too much of that over the years. There’s a surprise for Trixie and Star."

The original series, which ran from 2006 to 2008, was set in the 1870s, when Deadwood wasn't much more than a prospecting camp. The follow-up film jumps ahead a decade, to 1889 when South Dakota earned statehood.

But despite the passage of time, it looks like Al and Hearst are still at odds. And with Alma in the mix, no doubt her ex-lover Bullock will also get involved in any disputes that arise.

McShane also teased the possibility of a second sequel movie — even though this one took 12 years to make.

"It ends leaving you wondering,” he said of the ending.

"If it makes $115M, HBO will somehow find a way to do another one.”
