All you movie enthusiast , what was your opinion/theory for the cool, calm, collective Waltz abruptly shooting DiCaprio when going to shake his hand, without a plan, real motive, knowing it would end in losing gunfire? Seemed out of character, and Tarantino is such a master I doubt it was done on accident, just trying to figure out what the reason/ storyline was behind Waltz losing his cool? I Loved this movie and was hanging on every scene. However this scene left me with questions. Anyone else?
