Spoiler alert for 1930s play Gaslight
I learned today that the play Gaslight was renamed Angel Street in the US.
It was being performed as such into the 1970s
The other thing I learned (or, I guess, re-learned since I’ve seen the play twice) was that the ‘gaslight’ in the film isn’t actually part of the gas lighting.
The villain in the film is trying to make his victim think that they are going mad…but the gaslight effect is accidental.
