Nellie Oleson Star Surprises in Netflix Reboot

Alison Arngrim looked unrecognizable as she returned to the Little House on the Prairie franchise for the new  reboot - 43 years after the original series ended.

The actress, 64, famously played the role of Nellie Oleson over 104 episodes of eight seasons that ran from 1974–1982.

However, she returned as a new character for the long-awaited revival, which premiered on the streaming platform on Thursday.

Arngrim stars as 'crazy lady' Ida, who encounters the Ingalls girls during their search for John Edwards, in episode two.

Instead of Nellie's blonde ringlets and pastel bonnets, Arngrim's Ida has a much more disheveled appearance, with rotting teeth and visible dirt on her face.

Ida is among a group of frontier women who claim to know where Edwards is, and tell the girls that he is coming back soon.

When Laura (Alice ) senses danger and seeks to run away from the scene, Ida grabs her, leading Laura to bite her arm in an effort to flee.

The Daily Mail has reached out to representatives for Arngrim for further comment on the story. 

Arngrim, speaking with the Netflix site Tudum on Thursday, said she was cast in the series just weeks before cameras began rolling in Canada.
