An original Blood Oath Marker seen and used in Chad Stahelski's 2017 action hit John Wick: Chapter 2, the second installment of the acclaimed franchise starring Keanu Reeves as the legendary assassin.
In the film, John Wick is pulled back into the criminal underworld to repay a debt, only to discover a massive bounty has been placed on his life. The Marker is one of the most important objects in the John Wick universe: opening it reveals a divided surface recording the debt of a blood oath between two individuals. The debtor presses a bloody thumbprint on one side to commit that an oath is owed, and the debtee presses their own bloody thumbprint on the other side once the oath has been fulfilled. Within the films' meticulously built underworld, the issuance and redemption of these blood oaths are registered and tracked by The Continental under the supervision of Winston, and it is Santino D'Antonio's Marker, held over John's head, that sets the entire film in motion.
As the object that drives the plot of Chapter 2 and embodies the unbreakable rules of the assassins' world, the Blood Oath Marker stands as a true centerpiece of modern action film history.
