Director David Lowery is not a stranger to experimental or cerebral filmmaking, with his most popular example being the 2017 film, A Ghost Story. His latest experiment, The Green Knight, is adapted from the 14th century Middle English poem, Sir Gawain and the Green Knight, about a member of King Arthur's court in the middle ages who accepts the challenge to a game of beheading from the magical Green Knight, and a bargain to reunite one year in the future. This bargain sends the reluctant hero on a quest through the foggy English countryside where he tests his wits, strength, and virtue.
