What a dump!
When Martha says "What a dump!" at the beginning of Act One, she is quoting Bette Davis, who uses the same line in Beyond The Forest, a 1949 movie with Bette Davis and Joseph Cotten.
In this movie, Rosa (Bette Davis), a mill-town girl from Loyalton, Wisconsin, is married to Dr. Lewis Moline, a small-town Midwestern doctor. To escape her boredom, she begins an illicit and erotic affair with a vacationing neighbor.
The film begins with a warning statement: "This is the story of evil. Evil is headstrong - is puffed up. For our soul's sake, it is salutary 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."
