The epic fantasy adventure "The Green Knight", based on an Arthurian legend tells of the adventures of Sir Gawain (Dev Patel), King Arthur’s headstrong nephew who sets out on a bold quest to face the Green Knight, a giant, green-skinned stranger, and test of men. Gawain faces a host of ghosts and thieves as he tries to prove himself worthy in the face of the ultimate threat. Visionary filmmaker David Lowery gives a bold twist to a timeless tale about the knights at the table.
