But on Tuesday night in Hollywood, Ian McShane was the headliner at the premiere for HBO's Deadwood movie.

Spotlight: On Tuesday night in Hollywood, Ian McShane was the headliner at the premiere for HBO's Deadwood movie, a long-awaited follow-up to the series that ended in 2006

Deadwood ran for three seasons on the premium cable channel from 2004 to 2006.

HBO confirmed in July 2018 that the fan favorite would return in movie form and that most of the show's ensemble cast would be taking part.

The series was set in the 1870s in Deadwood, South Dakota, before and after the area's annexation by the Dakota Territory, and charted Deadwood's growth from gold rush camp to town.

Date night: McShane was accompanied to the screening by his American actress wife Gwen Humble, whom he wed in 1980

McShane and actor Timothy Olyphant starred as two of the town's real-life residents, brothel and bar owner Swearengen and sheriff Seth Bullock.

The movie picks up a decade after the end of the series in 1889 as the deadwood townsfolk celebrate South Dakota’s statehood.

Back in December, executive producer Carolyn Strauss spilled some beans about the movie plot to EW.com.

'It’s about the passage of time. The toll of time on people. It’s mellowed some people and hardened others,' Strauss explained.

'And it’s about the town’s maturing and becoming part of the Union and what that event sets in motion, in a very personal way for the people that it brings in town and what ensues.'

She went on: 'The time has taken its greatest toll on Swearengen. He’s the person who really drove so much of the life of the town and there’s a sense of that power waning somewhat, and what ensues of that is a big part of the story.'
