We at Collider are happy to exclusively debut a new poster for Warner Bros.’ upcoming fantasy actioner King Arthur: Legend of the Sword, designed by Shepard Fairey’s Studio Number One. Directed by Guy Ritchie, the film is a unique spin on the Excalibur legend starring Charlie Hunnam as the titular Arthur who is orphaned at a young age and grows up on the streets. But when he pulls the sword out of the stone, his life is upended and he crosses paths with the ruthless king Vortigem (Jude Law), who just so happens to have murdered his father.

This exclusive poster art is a twist on a playing card and posits Arthur and Vortigem as dueling kings, and it's celebrating Warner Bros.' "King for a Day" taking place this Thursday, April 27th.

 Here’s the official synopsis for King Arthur: Legend of the Sword:

When the child Arthur’s father is murdered, Vortigern (Jude Law), Arthur’s uncle, seizes the crown. Robbed of his birthright and with no idea who he truly is, Arthur comes up the hard way in the back alleys of the city. But once he pulls the sword from the stone, his life is turned upside down and he is forced to acknowledge his true legacy…whether he likes it or not.
