'Dune: Part Two' director Denis Villeneuve breaks down the glorious scene where Paul Atreides (Timothée Chalamet) uses the thumper for the first time to draw a sandworm out from beneath the surface as Chani (Zendaya), Stilgar (Javier Bardem) and the Fremen look on. Denis explains how he built the "most important" scene of the film over the course of 44 days, with the use of various sunlight levels and blending of visual effects to make it feel edgy and real.
