Alison Arngrim as Nellie Oleson
Known as the spoiled brat nemesis of Laura, Nellie Oleson was played by Alison Arngrim. And she is probably one of the best villain actresses of the small screen. According to Alison, she was abused as a child, and the liar and manipulative Nellie helped vent out all of her anger. After Nellie, she continued to act in TV, film, and even theater projects. She also wrote a biographical book, Confessions of a Prairie Bitch: How I Survived Being Nellie Oleson and Learned To Love Being Hated.
And then she became a start-up comedian, which she is doing until now. And since the pandemic canceled all of her stand-up shows, she turned to an online platform known as Stageit, and she currently hosts her shows right at the comfort of her own living room.
