Endeavour star opens up on filming "emotional" final scenes

“It was very moving, of course, especially in the last episode," he said. "Because, you know, you get to be doing the last scene ever on that set, with that actor. Say, with Caroline [O'Neill], who plays my wife, with Anton [Lesser], as Bright."

He also recalled filming a "really lovely" scene for the finale which featured all the regulars. "We'd never been all together for a scene before," he said. "So that was joyful, lovely, delightful."

Allam added that his final two scenes with star Shaun Evans were "very emotional: emotional to do and also emotional for the characters. And we were both quite pleased with how they worked."

He also explained that one particularly moving moment was a visit to see some of the show's music being recorded at a studio in Hampstead.

“I'd never been before, Shaun [Evans] had," he said. "There was this, something like a 50-piece orchestra. I've never realised. So to be in this room with this 50-piece orchestra playing Barrington's music and stuff like that, playing the theme for the last time ever? Well, none of us could speak."

He added: "It was also funny doing ADR. Because on my last day of ADR for the last episode, I sort of suddenly realised that I will never speak as Fred Thursday again. So that seemed very, very final. Unless there's a spin-off!”
