The two men form a strong bond, and Reid faith in Tolkachev is rewarded when he hands over a treasure trove of military secrets, resulting in Tolkachev earning the nickname “The Billion Dollar Spy,” and his actions altering the power balance between the East and West.
Billion Dollar Spy would have seen Armie Hammer playing Brad Reid, who arrives at the CIA’s Moscow station and strikes up a friendship with Mads Mikkelsen’s Adolf Tolkachev, a Soviet engineer.
Billion Dollar hasn’t begun production yet, so there’s still plenty of time for the creative minds behind the movie to find Hammer’s replacement, although there was no mention of anyone being specifically looked at.
