Gaslight (film adaptations)

"Gaslight" is a psychological thriller originally a 1938 play about a woman whose husband manipulates her into questioning her perceptions and sanity to hide his wrongdoing. The story was adapted into films, most famously in 1940 and 1944, where the term "gaslighting" originated. In these movies, the husband secretly alters their environment and insists she’s imagining things, causing her doubt and confusion. The adaptations highlight themes of manipulation, psychological control, and the erosion of trust, illustrating how emotional abuse can undermine an individual’s confidence in their own reality.
