David Lowery’s The Green Knight (2021) reimagines the 14th-century Arthurian poem Sir Gawain and the Green Knight into a visually arresting and thematically rich cinematic experience. Starring Dev Patel as Gawain, the film follows King Arthur's nephew as he accepts a mysterious challenge from the enigmatic Green Knight, leading him on a perilous quest filled with supernatural encounters and moral trials. This journey forces Gawain to confront his own notions of honour, courage, and destiny.
Filmed across the lush landscapes of Ireland, including locations like Cahir Castle in County Tipperary and Charleville Castle in County Offaly, the movie's setting enhances its otherworldly atmosphere. These historic sites provide a tangible connection to the medieval world, grounding the film's fantastical elements in real-world locations.
Released in U.S. theaters on July 30, 2021, by A24, The Green Knight garnered critical acclaim for its bold storytelling and striking visuals. While it is available for streaming on platforms like Amazon Prime Video, its presence on Netflix varies by region.

Beyond the film, The Green Knight has also inspired adaptations in other media, such as the character unlockable in the video game Castle Crashers, showcasing the story's enduring appeal and versatility.
