Now I know what "gaslight" means - see Cukor's 1944 film

Well, at least now I know what "gaslight, v." means, having watched George Cukor's 1944 b/w movie of the same name (based on a play - and at times quite evidently so, w/ very stagy dialog between the insidious Gregory - Charles Boyer - and the victimized Paula - Ingrid Bergman). Bergman, tricked by Boyer into thinking that she's losing her mind, is the main reason to watch this movie, especially her really weird "mad" scenes (in particular, at when she's pushed to burst into tears and hysterics at the piano recital) and her, at last!, rising up in power at the end of the movie. The plot is absurd, not believable for a minute, but thanks to the fine performances that Cukor elicits not only from the two leads but even from some of the comical minor characters - Angela Lansbury's portrayal of a snide and cocky house servant and the hilarious small part of the nosy London neighbor - the film will hold your attention start to finish - more than you can say for most Hollywood studio films from 75 years back.
