Kirill is an antagonist in the 2014 film John Wick.
He is one of Viggo Tarasov's henchmen and his head of security and is tasked with protecting Viggo's son Iosef. Of all of Viggo's men, Kirill is the only one that can actually defeat John in a fight, and came the closest to killing him.
He is portrayed by Daniel Bernhardt.
When John Wick invades the club Iosef visits, he is spotted by Kirill who watches the camera feed in a control room. Kirill recognizes Wick, draws his weapon and storms out of the room. After John manages to kill a whole divison of Kirills men, he gets shot by Kirill, but survives thanks to a bullet proof vest. Kirill manages to disarm Wick and a fight erupts. But John may have underestimated Kirill, as he defeats John within moments, beating the hell out of John, before throwing him off a balcony, but in return gets almost shot by John who still had a gun hidden in his belt. Kirill survives the shootout at the club, as did Iosef, cause their brawl allowed Iosef to escape unharmed.

John manages to break free and fights against Kirill, after a long violent fight, John strangles Kirill to death with his handcuffs still on.
