Gaslighted

I highly recommend the 1944 version of Gaslight. Ingrid Bergman has a fine turn as an opera singer (who we first glimpse performing Lucia de Lammermoor) whose debonair continental husband slowly convinces her she is mad, and Charles Boyer is delightfully evil as that Old Hollywood staple, a jewel thief. The film's title has made its way into the modern lexicon. Have you ever been gaslighted?
