Rivera's 3D Blender Model 10y in the Making-shows Greer Dragging Limo to Curb/Storm Drain for Shot

Dark Complected Man not showing his fist per Rich Dellarosa could be due to the film manipulation. The event Rich described clearly did not happen in the extant film. I could be missing something, but it seems wrong that his hand had to be open in the real footage. But I don't know what went into that model.
