Towards the end of the film, Judith Starkadder can be seen reading tarot cards. The one that she has in her hand is "the Sun". This is considered to represent "earthly happiness" in tarot interpretation.
The Jane Austen quote - "What a pleasant life may be had in this world by a handsome, sensible old lady of good fortune blessed with a sound constitution and a firm will." - is fictitious and not from any Jane Austen book or other writing.
