He continued: “It just got me thinking, I really wanted to see him in a red coat. I thought, it’s a total 180° or 360°… Everything that he’s had history with – like Jack Randall, Ardsmuir Prison, Culloden and fighting for his people – it signifies everything he’s fought against.

“And I thought it would be a really interesting place for Jamie to have to wear that and take that on board. And, as we know, Jamie is a man of honour and a man of his word, so it’s going to be a really tough thing to do.”

Heughan also talked about his involvement in making the new season, since becoming a co-producer with on-screen wife Caitriona Balfe: “We got the credit quite late on in the process and we weren’t really part of breaking the scripts down initially.

“As the seasons went on we had more and more say and were involved a lot more with the writing. I think with the last two episodes – especially the finale – we were really heavily involved in. There’s some big stuff this season, the finale is probably our most dramatic finale.”
