Set in the early 1970s, the final season finds Endeavour and Thursday entering a new era of change both professionally and personally with the return of some familiar faces along the way including Sam, played by Jack Bannon (Pennyworth), who arrives back from Northern Ireland following his service in the British Army.

Filmed in and around Oxford, the ensemble cast reunited with Shaun and Roger includes Anton Lesser (Killing Eve, Game of Thrones) who returns as CS Reginald Bright, Sean Rigby (Gunpowder) as DS Jim Strange, James Bradshaw (Close to The Enemy) as Dr Max DeBryn, Abigail Thaw (Miss Scarlet and the Duke) as Dorothea Frazil, Caroline O’Neill (The A Word) as Win Thursday and Sara Vickers (Watchmen) as Joan Thursday.

The final installment of the popular drama has once again been written by Endeavour creator Russell Lewis who has penned each of the 36 episodes across the last decade.
