Jaqen H’ghar — Brad Pitt
Jaqen H’ghar remains one of the great mysteries of Thrones. What were his motives, where did he go after helping Arya, did he even really exist? All questions we may never find answers to, but he remains an interesting character nonetheless. Although H’ghar plays a bit smaller of a role than Brad Pitt is accustomed to, we believe the Fight Club, Burn After Reading, 12 Years A Slave, and Once Upon a Time in Hollywood star would do great in the role of the deadliest assassin in Westeros.
