Fans stunned as E.B. White's 'Stuart Little' turns out to be a tiny human, not a mouse

Stuart Little character from 1999 film

Stuart Little isn't who you think he is and fans were shocked to learn that in E.B. White's 1945 children's book Stuart Little, the titular character isn't a mouse as depicted in the films, but a human child who looks like a mouse.

In White's 1945 book, the character has a much different origin story, as the beginning of the book reads, "When Mrs. Frederick C. Little's second son arrived, everybody noticed that he was not much bigger than a mouse."
