What a dump!
When Martha says at the beginning of Act One, "What a dump!" she quotes Bette Davis saying that same line in Beyond The Forest, a 1949 movie with Bette Davis and Joseph Cotton.
In this movie Rosa (Bette Davis), a Loyalton, Wisconsin, mill town girl, married to the small-town Midwestern doctor, Dr. Lewis Moline, engages in an illicit, erotic love affair with a vacationing neighbor to escape her boredom.
The film begins with a warning title: "This is the story of evil. Evil is headstrong - is puffed up. For our soul's sake, it is salutory for us to view it in all its ugly nakedness once in a while. Thus may we know how those who deliver themselves over to it end up like the Scorpion, in a mad frenzy stinging themselves to eternal death."
