Gaslight

1944 film Gaslight, starring Ingrid Bergman and Charles Boyer. The clip is significant because it shows the beginning of Boyer's character, Gregory Anton, gaslighting Bergman's character, Paula. He is already trying to control her and isolate her from her friends and family. He is also lying to her about what he is doing, which is a sign of his manipulative nature.
