The movie that Sheri picked up for herself is called Mourning Becomes Electra. It was originally turned into a movie in 1947, and then re-made in 1978 and is an adaptation from a Eugene O'Neill play.

Summary:

Eugene O'Neill's updated version of the Orestaia. In New England, after the American Civil War, a war-weary Agamem--er, Ezra Mannon comes home to his unhappy wife (Christine) and loving daughter (Lavinia). But Lavinia's ex-suitor, Adam Brant, has become Christine's lover, and together Adam and Christine plot to poison Ezra. When they succeed, Lavinia turns to her brother Orin to help bring the lovers to justice, but when they succeed, Orin goes mad and his suicide note may come between Lavinia and her new suitor, Peter Niles.

I think I will just read the Sunday paper on the couch while she watches the movie. She has always been the one into literature and good writing in the family.
