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.

Guilt brought siblings Louise (Marin Ireland) and Michael (Michael Abbott, Jr.) to make their ways back to the rural Texas family farmhouse on the news that their father (Michael Zagst) didn't have much time left. Their oddly distant mother (Julie Oliver-Touchstone) asserted that they shouldn't have come... and as a foreboding, unearthly force makes it's presence slowly known, she might be proven right. Bryan Bertino's chilling study also stars Xander Berkeley, Ella Ballentine. 95 min. Widescreen; Soundtrack English.
