The Richest Girl in the World is a 1934 American romantic comedy film directed by William A. Seiter and starring Miriam Hopkins, Joel McCrea and Fay Wray.

He goes to such great lengths to protect her privacy that, though she has grown into adulthood and acquired the title of the richest girl in the world, the newspapers do not have an up-to-date photograph of her.

She returns to America, but asks her friend and secretary, Sylvia Lockwood, to impersonate her in a meeting with the managers of her trust fund, who also do not know what she looks like.

After seeing how happy Sylvia is with her new husband, Phillip, she broaches the topic of setting a wedding date with Donald, her longtime fiancé.

Connors, Sylvia, and Phillip arrive a day late, using the bad weather as an excuse to give Dorothy time alone (except for the servants) with Tony.

Then, finally realizing who he really loves, he picks Dorothy up and carries her off to get married, still not knowing her true identity, and in spite of what he believes she did the night before.
