Timothy Olyphant has become the latest star to sign up for a role in season two of Disney+ series The Mandalorian.

The Justified actor will play a top-secret role in the upcoming season, due to launch on Disney+ in October, according to The Hollywood Reporter.

Olyphant mostly recently starred in Netflix series Santa Clarita Diet and is also known for roles in HBO's Deadwood (2004-06) and the movies Hitman (2007) and Live Free or Die Hard (2007). He joins previously-confirmed guest stars for The Mandalorian's new season including Terminator star Michael Biehn and Temuera Morrison, who will play fan favourite character Boba Fett.

The show's season two episodes will also feature links to the animated series Star Wars: The Clone Wars and Star Wars Rebels, with Rosario Dawson playing Ahsoka Tano in that character's live-action debut and Katee Sackhoff also playing Bo-Katan Kryze in live-action, a character she previously voiced on both The Clone Wars and Rebels.

Directors assigned to the new season of The Mandalorian include Robert Rodriguez (From Dusk Till Dawn) and Peyton Reed (Ant-Man), joining the returning Dave Filoni and series creator Jon Favreau.

Carl Weathers, who plays Greef Carga on series, is also expected to direct an episode, though JoJo Rabbit's Taika Waititi will not be back in the director's chair, with the Oscar winner instead helming a new Star Wars movie outing.
