Early in Peter Jackson's first Lord of the Rings film, The Fellowship of the Ring, there is a scene where the four Hobbits
Frodo Baggins, Samwise Gamgee, Meriadoc Brandy buck, and Peregrine Took – are hiding from one of the Nazgul. The four Halflings crawl into a hollow under the roots of a great oak tree while the Nazgul searches for them
coming very close indeed. So close, in fact, that at one point it hovers over them, filling the Hobbits with overwhelming fear
The Nazgul remains shrouded in its black cloak, the only part visible is the iron gauntlet that it grips the twisted oak roots with – and even the slight glimpse of that gauntlet is enough to instill a deep sense of dread
