Walden Media’s Cold War thriller Billion Dollar Spy has added Vera Farmiga.

She joins Russell Crowe and Harry Lawtey. Farmiga will play Natasha, Adolf Tolkachev’s (Crowe) wife.

It follows “Adolf Tolkachev (Crowe), who in real life risked everything to pass thousands of pages of top-secret Soviet intelligence to the U.S. Despite repeated rejections by a wary CIA, Tolkachev persisted, embodying the courage to stand against a regime that betrayed its own people.

Finally finding an ally in CIA agent Tom Lenihan (Lawtey), Tolkachev was able to shift the balance of power, proving that true patriotism lies not in blind allegiance, but in the willingness to challenge a government when it strays from its ideals.”

The film is adapted from David E. Hoffman’s book and is directed by Amma Asante. Stephen Gaghan wrote the most recent draft, revising a script penned by Ben August.

Deadline first reported Farmiga’s casting.
