Damian Lewis won multiple awards as terrorist-turned-CIA agent Nicholas Brody in Homeland, and is now hoping to replicate that success in a gritty new role as a ruthless MI6 spy.
The actor will walk the red carpet later at the UK gala premiere of Our Kind Of Traitor, an adaptation of a John Le Carre thriller.
Joining him will be Spectre star Naomie Harris, who has shared the screen with her fair share of spies.
She plays holidaymaker Gail, who is caught up in the world of dirty politics and international espionage with her husband Perry (Ewan McGregor) when they accidentally befriend a Russian mafia kingpin in Marrakech.
Director Susanna White, the woman behind Parade's End and Nanny McPhee And The Big Bang, will also be at the premiere at the Curzon Mayfair.
Le Carre's spy novels have seen a resurgence in recent years with the Oscar-nominated film Tinker Tailor Soldier Spy in 2011 and the recent BBC adaptation of The Night Manager, starring Tom Hiddleston.
Our Kind Of Traitor will be released in cinemas on May 13.
