When Paul, Duke, Gurney, and Kynes go on an aerial inspection of the spice mine, they witness a dangerous situation when a carryall fails to rescue a crawler with several workers inside as a sandworm wriggles progressively near underneath the desert surface.
In the adrenaline-filled scene from the movie, Paul has a vivid prescience in the middle of the desert as he's helping the workers escape, which renders him sitting motionless in the sand as the sandworm approaches. Eventually, Gurney comes and jolts Paul out of his reverie and saves his life by the skin of his teeth. However, in the book, Paul never leaves the ornithopter. Instead, he watches in horror as the wrath of the sandworm unfolds from the safety of their aircraft.
