One Christmas in Camelot, the revels were interrupted by a hulking, emerald-skinned knight (Ralph Ineson), who dared anyone present to lay a blow on him... as long as he got to strike back a year later. The king's impetuous nephew Gawain (Dev Patel) met the challenge-and after the intruder improbably survived, faced a fateful journey to meet his end of the bargain. David Lowery's stylish, subversive take on the Arthurian tale co-stars Alicia Vikander, Joel Edgerton, Sean Harris. 130 min. Widescreen; Soundtrack English. Two-disc set.

Widescreen; Soundtracks English DTS HD 5.1 Master Audio, French Dolby Digital 5.1; Subtitles English (SDH), French; featurette; audio commentary; behind-the-scenes footage.
