Fan Casting Dmitriy Popov in Zack Snyder's Rainbow Six

An ex-KGB agent turned freelance terrorist consultant who sips wine in five-star hotels and trades stocks on his own attacks. He kills a man in two moves to prove he's "not as rusty" as he thought, then chokes a second on horseback when the man's laughter offends him. Amoral but not stupid, he becomes the unlikely informant who tips off Rainbow Six to Brightling's omnicide plot. He is John Clark without a country, without a team, and without a Sandy—and in the end, Clark lets him walk.
