Matthew McConaughey's scenes were shot on the second week of filming. The chest beating and humming performed by him was improvised and a warm-up rite that he performs before acting. When Leonardo DiCaprio saw it while filming, the brief shot of him looking away uneasily from the camera was him looking at Martin Scorsese for approval. DiCaprio encouraged them to include it in their scene and later claimed it "set the tone" for the rest of the film. 🎬 The Wolf of Wall Street (2013) | Best Of Mov
