Alison Arngrim, who originated the role of villain Nellie Oleson in the classic "Little House on the Prairie" series, has made a surprise cameo in Netflix's new reboot, now streaming. The nostalgic tie-in is designed to bridge fans of the original show with a new audience for the reimagined adaptation, and Arngrim has offered advice for Willa Dunn, the child actress now playing Nellie.

Arngrim, who has not yet met Dunn in person, spoke about how to master the art of playing a character audiences love to dislike, drawing on her own experience in the iconic role. The new series also features actor Warren Christie, who has said he hopes the reboot will unite longtime fans of the original with newcomers discovering the story for the first time.
