I'm giving myself a night off with a borrowed copy of "Suddenly, Last Summer," a 1959 film based on a Tennessee Williams play. Katharine Hepburn plays the scary widow Violet Venable, who wants to give Elizabeth Taylor's character a lobotomy. Taylor makes sarcastic remarks about having to shave her head. It is great so far. (I'm turning it off halfway through to go to bed, as my day hours have turned me into an old lady.) Violet has a carnivorous plant that she addresses as "my wicked lady" and labels a Venus flytrap, although it appears to be a fake Nepenthes. She also appears to have a giant Amorphophallus in her garden; it stands not-so-subtly behind Montgomery Clift's doctor character as they converse.
I am grateful to Barry at the marvelous Carnivorous Plant FAQ for making me aware of this film.
