The Slim Princess is a 1920 American silent comedy-drama film starring Mabel Normand, directed by Victor Schertzinger, produced by Samuel Goldwyn, and written by Gerald C. Duffy based on a musical play of the same name by Henry Blossom and Leslie Stuart,[1] which was from a story by George Ade.

Her younger sister, weighing in the neighborhood of 300 pounds and who is also the family favorite, is sought by the eligible men of the court.

American millionaire Alexander Pike (Thompson) sees the princess and immediately falls in love with her, and is then hounded from the country by the police of her father.

The princess is later sent to America to partake of a patent fat producer that is widely advertised, and meets Alexander at the Ambassador's ball.

When Alexander, whose millions are no less powerful in Morovenia than in America, arrives, he convinces her father of his love for Kalora, marries the princess, thus opening the way to the altar for the second daughter, and all are happy.
