Edward Snowden sits on his hotel-room bed, about to keystroke a password into his laptop. Without looking particularly sheepish about it, he drapes a blanket over his head and upper body, so he can comfortably input the information without being observed. This gesture evokes many things: a kid reading a book under the covers at night; the Elephant Man disguising his grotesqueness; a conspiracy theorist muttering warnings about cosmic rays coming through his skull. None of these associations is unjustified, and all underscore the absorbing character study that Citizenfour presents in you-are-there fashion.
