Jensen Ackles is joining his former TV brother Jared Padalecki on the cowboy circuit.

While Padalecki roams the Texas range on The CW’s Walker, Ackles will saddle up for a big screen rodeo, joining the cast of the Western feature Rust.

Ackles joins Alec Baldwin, Travis Fimmel, Brady Noon and Frances Fisher in the film, written and directed by Joel Souza. Baldwin will produce the film.

The movie tells the story of infamous Western outlaw Harland Rust (Baldwin), who has had a bounty on his head for as long as he can remember. When his estranged 13-year-old grandson Lucas (Noon) is convicted of an accidental murder and sentenced to hang, Rust travels to Kansas to break him out of prison. Together, the two fugitives must outrun the legendary U.S. Marshal Wood Helm (Ackles) and bounty-hunter Fenton “Preacher” Lang (Fimmel) who are hot on their tail. Deeply buried secrets rise from the ashes and an unexpected familial bond begins to form as the mismatched duo tries to survive the merciless American Frontier.

Ackles spent 15 seasons on The CW show Supernatural, and recently started work on the role of Soldier Boy in the highly-anticipated third season of the Emmy nominated The Boys. This will be the first non-voiceover role Ackles has had in a movie since he starred in 2009’s My Bloody Valentine 3D.

No release date has been set for the movie.
