Damian Lewis and Guy Pearce star in ITV's espionage thriller series A Spy Among Friends which will be airing on the broadcaster soon.
It dramatises the true story of Nicholas Elliott (Lewis) and Kim Philby (Pearce), two British spies and lifelong friends.
Additionally, the series is based on the book of the same name by Ben Macintyre.
An official synopsis on the Radio Times website reads: "Philby was the most notorious British defector and Soviet double agent in history. This is a story of intimate duplicity; of loyalty, trust and treachery.
"Philby’s deeply personal betrayal, uncovered at the height of the Cold War, resulted in the gutting of British and American Intelligence."
