I think they put her head on wrong.
Did this Laff cover stop her career cold? Hard to say. Judy Landon, who had appeared as “third extra in crowd scene” and “small pinkish biped glimpsed for a second in the background,” saw her roles dry up after 1953. She would have one more job worthy of imdb’s notice: a Brady Bunch episode 20 years later.
Imagine if you were married to her, and she turned her head and made that face every time you came into the room. It would creep you out after a year or two.
