From IMDb review:
"Sir Gawain and the Green Knight" is a late 14th-century Middle English chivalric romance. It is one of the best known Arthurian stories and is of a type known as the "beheading game". The Green Knight is interpreted by some as a representation of the Green Man of folklore and by others as an allusion to Christ.. . It describes how Sir Gawain, a knight of King Arthur's Round Table, accepts a challenge from a mysterious Green Knight who challenges any knight to strike him with his axe if he will take a return blow in a year and a day. Gawain accepts and beheads him with his blow, at which the Green Knight stands up, picks up his head and reminds Gawain of the appointed time.
