The Little Drummer Girl, which stars Alexander Skarsgard, has revealed a scene at the Acropolis in Greece did not go ahead until “months of negotiations”.
Greece’s Central Archaeological Council had initially prohibited filming at the ancient ruins.
Fortunately, Greece’s Prime Minister Alexis Tsipras gave the cast and crew the go-ahead to film at the ancient ruins.
Talking to Harper’s Bazaar UK, Alexander said: “That was months and months of negotiations.
“They hadn’t opened up for a film crew for 70 or 80 years and to be able to shoot up there, just us in an entire night was absolutely extraordinary, and something I’ll never forget.”
The 42-year-old also admitted to the publication people from the government had to oversee the filming to ensure it was done respectfully.
He continued: “It was a lot of negotiation – even that night they had people from the government that oversaw it and that we had to negotiate to get certain shot, and [to make sure] that we got what we needed and portrayed in a respectful way.”
The Little Drummer Girl is the latest John Le Carre adaption by the Cornwell brothers who were behind The Night Manager.
The thriller is set in the 1970s during the Israeli-Palestine conflict.
The official synopsis reads: “Brilliant young actress Charlie strikes up an acquaintance with an intriguing stranger while on holiday in Greece, but it rapidly becomes apparent that his intentions are far from romantic.
“The man is Becker, an Israeli intelligence officer, who entangles her in a complex and high stakes plot orchestrated by Spymaster, Kurtz.
“Set in the late 1970s yet sharply contemporary, The Little Drummer Girl weaves a dynamic and exciting story of espionage and international intrigue; of love and betrayal.“
Alexander Skarsgard plays Becker, an Israeli intelligence officer who seduces Charlie a radical left-wing actress played by Florence Pugh.
Florence is best known for her leading role as Lady Macbeth where she won a the award for Best Actress at the British Independent Film Award.
Producer Steven Cornwall said at a BBC preview: “You really travel the journey with Charlie.
“You share her experience and you travel through what is the operational story from a particularly personal, emotional and shared experience and discovery of character in a way which is as important as the discovery of the plot.”
Alexander is best known for his role as Eric Northman in the HBO series True blood and as Perry Wright in Big Little Lies.
Other cast members include Clare Holman, Michael Moshonov and Charles Dance.
The Little Drummer Girl airs on BBC One tonight at 9pm.
