"The Fountainhead" became a worldwide success, bringing Rand fame and financial security. In 1943, Rand sold the rights for a film version to Warner Bros. and she returned to Hollywood to write the screenplay. Finishing her work on that screenplay, she was hired by producer Hal B. Wallis as a screenwriter and script-doctor. Her work for Wallis included the screenplays for the Oscar-nominated "Love Letters" and "You Came Along". Rand also worked on other projects, including a planned nonfiction treatment of her philosophy to be called "The Moral Basis of Individualism". Although the planned book was never completed, a condensed version was published as an essay titled "The Only Path to Tomorrow" in the January 1944 edition of "Reader's Digest" magazine.
