In the atmospheric Southern drama Undertow, directed by David Gordon Green and produced by Terrence Malick, Lisa Muskat, and Edward R. Pressman, two brothers find their lives upended by a dangerous family secret. The film follows the younger sibling, played by Jamie Bell, and his impressionable little brother, portrayed by Devon Alan, as they live a sheltered, rural existence with their reclusive father, Dermot Mulroney. Their fragile peace is shattered with the arrival of their charismatic but volatile uncle, brought to life by Josh Lucas. His presence unearths a long-buried conflict and triggers a chain of violent events, forcing the boys to flee into the surrounding wilderness. On the run, they encounter various figures from the Georgia backwoods, including a brief but pivotal appearance by Kristen Stewart, alongside Shiri Appleby, Robert Longstreet, Eddie Rouse, and Patrice Johnson. Co-written by Green and Joe Conway, this 107-minute, R-rated tale is a gritty and mythic story of betrayal, survival, and the powerful, often perilous, pull of family legacy.
