Melissa Gilbert was 15 when she kissed Dean Butler on screen
The story starts with a young Laura Ingalls, but in later years she is old enough to date and even marry. The show’s producers intentionally cast Melissa Gilbert for her flexible age, but she was a little young for kissing. Then they asked her to kiss her costar, Dean Butler. He was 23, but Gilbert was only 15 years old. Needless to say she survived, but scary.
