Harry explained: "We jump to Libya for part of the story, so doubling that was trickier to ensure you get those sandy visuals.

"We also go to the south of France, which is not so hard to double in Greece - it's always just finding the right location."

The programme was shot in Greece, specifically Athens, and the cast had previously discussed the harsh filming conditions as they battled against sweltering temperatures.

Jack continued: "It's an ambitious show. There's a lot of action and locations and there were concerns about how we'd do it.

"But we did have a great company we were working with in Greece and a great team who managed to somehow bring it all to life without anything being compromised."

Actress Hawes confessed she had to handle some enormous stunts, but relished the challenge. "This is some of the biggest stunt work that I've ever done," she revealed.

"I love a challenge and some of this has been really challenging in a good way.

"In The Assassin there's some stunt-heavy scenes and it's broken up with brilliant bits of dialogue which adds great humour to the series.

"Those scenes in the show don't take themselves too seriously, which sets it apart from other more serious action series I've worked on, such as Bodyguard and Line of Duty."

Mo Lee, who served as the stunt co-ordinator on the series, confessed "every project is a challenge."

He shared: "I need to find out what everyone wants, what I need to get that looks good: dramatic and stunty. Everything is challenging but to me, that is the best part.

"Because, once you do create something which is great, then it's a nice achievement."
