Signs (2002)

Written and directed by M. Night Shyamalan, *Signs* stages a global alien invasion entirely from the vantage of a single Pennsylvania farm^[1]. Graham Hess, a former priest who lost both his wife and his faith, finds a huge crop circle pressed into his cornfield; soon matching patterns and lights hovering over cities appear around the world. The film almost never shows the aliens directly, building dread instead from news broadcasts, bolted doors and the dark of a basement — an invasion reduced to a claustrophobic home siege. Crop circles are cast as the invaders' navigation markers, a setup familiar from pop culture but disconnected from the documented record^[3]. Released a year after 9/11, it is most often read as a parable about fear and belief rather than a monster movie.
