The Billion's actor, shortly after ending his role on the show, has already signed on for a new project. Lewis will play opposite Guy Pearce in a new Brit Box/Spectrum limited series titled A Spy Among Friends. The show is based on the New York Times's best selling book by Ben MacIntyre.

MacIntyre is a British author who finds his best selling stride within the realm of historical spy fiction. A Spy Among Friends is one of these books. (Shocking, I know.) Set in the heart of the Cold War, the story chronicles the true story of friendship and betrayal between Kim Philby (Guy Pearce), a soviet spy, and Nicholas Elliot (Damian Lewis), the man who thought he knew him.

In an account with the Hollywood Reporter, Lewis exclaimed:

I'm excited to be producing and starring in A Spy Among Friends. These fabulous scripts by Alex Cary take an up-close look at friendship - a friendship that was blinded by love, class, and membership to the right clubs, and ended in betrayal and the deaths of thousands. It's been a fantastic creative process developing Spy and now I can't wait to start filming with Guy and all the other brilliant actors who've happily agreed to join us.

While fans of his Lewis's are upset he will not be returning to his hedge fund manager role, don't worry. There will be Billions more chances to see him. (Sorry, I couldn't resist!)

A Spy Among Friends comes out on Brit Box and Spectrum On Demand in the Fall of 2022.
