Paramount+ has dropped the first teaser trailer for Lawmen: Bass Reeves, the Western drama from Yellowstone creator Taylor Sheridan that's been filming around North Texas for months, and it seems "wicked days" are ahead.

Sheridan's new series stars British actor David Oyelowo as Bass Reeves, a former slave who became one of the first Black U.S. deputy marshals west of the Mississippi River in 1875. Reeves is believed to have been the inspiration for the fictional character the Lone Ranger.

Originally announced as a Yellowstone spinoff called 1883: Bass Reeves, the title has changed, and it's now not considered part of the Yellowstone universe, a rep for the show says. None of the Yellowstone/1883/Dutton family characters will be in the show.

In the 20-second teaser, Oyelowo rides a horse across a field and introduces himself as Reeves in a voiceover. "I'm the law of this land, I'm Deputy U.S. Marshal Bass Reeves," he says. Then he then looks directly into the camera and declares, "and your wicked days are done."

There are flashes of guns shooting, cannons firing, and a house burning. A tagline reads: "The legend you know. The truth you don't."

According to Vanity Fair, Lawmen: Bass Reeves will be an eight-part anthology series that will premiere later this year on Paramount+. Sheridan and Oyelowo are executive producers.

The cast includes Dennis Quaid, Donald Sutherland, Mo Brings Plenty, Lauren E. Banks, Demi Singleton, Forrest Goodluck, and Barry Pepper.

Fort Worth mayor Mattie Parker announced in September 2022 that Bass Reeves filming would be coming to Fort Worth, following Yellowstone prequel 1883, which filmed around the city in 2021. Sheridan is an honorary Fort Worthian who attended Pascal High School and lives on a ranch in Weatherford.

Shooting for Bass Reeves started in early 2023, and many locals were cast as extras. The production was based in Fort Worth and scenes were filmed in Weatherford, Waxahachie, Stephenville, and Palo Pinto County.

"We were honored to have this production based in Fort Worth during filming and are looking forward to the series premiere later this year," the Fort Worth Film Commission posted on Facebook with a link to the trailer.
