The Revenant (2015), "The Bear Attack"
It might just be the single most confronting, can't-look-away-from scene in a film released this past decade. The bear attack in Alejandro G. Iñárritu’s The Revenant is six heart-wrenching minutes long and almost documentary-like in the way it holds its gaze at Leonardo DiCaprio as the frontiersman Hugh Glass and the grizzly that confronts him.
The realization of the iconic one-take scene required close collaboration between a number of film departments: directing, cinematography, stunts, makeup, costume, and, of course, the visual effects artists behind the CGI bear, Industrial Light & Magic (ILM). To shoot the scene, DiCaprio acted with stand-in blue-screened stunt performers on the forest floor, who sometimes wore extra padding for the proper bear proportions. The actor was also pulled on wires to create the bear's jerking motions.
