It is unfortunate that Agnes Moorehead is largely known to baby boomers and subsequent generations by her most famous TV character, the one-dimensional "Endora," mother of Samantha the witch on "Bewitched" (and unloving mother-in-law of the much-put-upon Darrin Stevens). She was one of the most interesting and versatile character actresses for over three decades, from her first film role as the birth mother of the title character in "Citizen Kane" until her untimely death from cancer in the early 1970s. Her other roles included the working-class aunt of the title character (played by Jane Wyman, Ronald Reagan's ex) in the rural-Canadian-set melodrama "Johnny Belinda," a woman with evil intent in the Bogart/Bacall noir "Dark Passage," and the shrewish but benevolent maid who tries (and fails) to save the title character (Bette Davis) from evil plotters in the Grand Guignol horror classic "Hush, Hush...Sweet Charlotte." In this justly-beloved episode of "The Twilight Zone" (with a none-too-surprising twist ending which will not be revealed here), Moorehead is a simple hard-working rural woman living alone in a farmhouse who is besieged by little space-suited men armed with ray guns. She protects herself and her homestead with absolutely no dialogue, and demonstrates a range of emotions, especially a very convincing terror, as she confronts the intruders on her peaceful rustic retreat.
