Matthew McConaughey's bizarre, rhythmic chest-thumping and humming routine in The Wolf of Wall Street was actually just an acting warm-up exercise he used to relax his vocal cords before filming. Leonardo DiCaprio noticed his co-star doing the strange ritual between takes and suggested they roll the cameras and incorporate the absolute lunacy directly into the crucial diner scene. Director Martin Scorsese loved the improvised moment so much that it became the defining thematic anchor for a three-hour epic about cocaine-fueled stockbroker corruption and financial degeneracy.
