Pippa Scott is brilliant in this -
as one review mentioned, she hardly has a word of dialog as the reverend's wife, yet is remembered as much as anyone in the film.
However (and perhaps because she has so little dialog), what does the scene mean where she stares at her cheeks after making love? Does she see herself flushed? And why the stacking of Oreo cookies in the kitchen - and begging Van Dyke not to turn on the light? I assumed (due to the frequent sex references) that perhaps she was pregnant and the Oreos were her cravings? What do others think?
