Gaslight is an adaptation of a Patrick Hamilton play and a remake of the 1944 classic starring Charles Boyer and Ingrid Bergman that garnered seven Oscar nominations, including a win for Bergman. It also introduced the film's title into the vernacular, as the act of "gaslighting" someone means to drive them insane. It is being scripted by Abi Morgan and directed by Joe Wright.

The first gaslight was yellow, smelly, smoky, and very hot. Brilliant white gaslight was not made possible until the invention of special incandescent gas mantles in the 1890's
