THE BBC has announced the new guest cast for the return of hit crime drama Shetland.

Acclaimed actor Ian Hart (Mr Bates vs The Post Office, Harry Potter) and Vincent Regan (Traces, Aquaman) lead the guest cast alongside series favourites Ashley Jensen (below) and Alison O’Donnell as filming begins on the new series.

The National:

Shetland will film in locations around Scotland as well as in the Shetland Isles over the coming months, with the series debuting on BBC One and iPlayer later this year.

Originally based on the award-winning novel series by crime writer Ann Cleeves, the new series sees DI Calder (Jensen) throw in in at the deep end after a friend of Tosh’s (O’Donnell) goes missing.

Hart, who starred as Professor Quirrell in the first Harry Potter film said: “I’m looking forward to embarking on a Shetland adventure – it’s a place I’ve always wanted to visit and to do so with this incredible drama is wonderful.”

Other guest stars in the upcoming series include Stuart Campbell (SAS Rogue Heroes, Baptiste) and Robert Jack (Annika, Damaged).

Regan meanwhile commented: “I’m thrilled to be joining the cast of Shetland which is such a beloved BBC drama.

“My character and his family are at the heart of this dark and twisting storyline and I’m looking forward to seeing how it all unfolds.

“The opportunity to visit the Shetland Isles was also a real pull to the part as well as working with the likes of Ashley Jensen and Alison O’Donnell.”

The BBC reports that the last series averaged seven million viewers across its run with the drama becoming the second-biggest in Scotland across all channels and streamers, behind Happy Valley.

The ninth series was part of a double commission recently announced by the BBC while series 10 of Shetland will be filmed in 2025.
