text: The success of The Fountainhead brought Rand fame and financial security.In 1943, she sold the film rights to Warner Bros.and returned to Hollywood to write the screenplay.Producer Hal B.Wallis then hired her as a screenwriter and script-doctor for screenplays including Love Letters and You Came Along.Rand became involved with the anti-Communist Motion Picture Alliance for the Preservation of American Ideals and American Writers Association.In 1947, during the Second Red Scare, she testified as a "friendly witness" before the United States House Un-American Activities Committee that the 1944 film Song of Russia grossly misrepresented conditions in the Soviet Union, portraying life there as much better and happier than it was.She also wanted to criticize the lauded 1946 film The Best Years of Our Lives for what she interpreted as its negative presentation of the business world but was not allowed to do so.When asked after the hearings about her feelings on the investigations' effectiveness, Rand described the process as "futile".After several delays, the film version of The Fountainhead was released in 1949.Although it used Rand's screenplay with minimal alterations, she "disliked the movie from beginning to end" and complained about its editing, the acting and other elements.Atlas Shrugged and Objectivism Following the publication of The Fountainhead, Rand received many letters from readers, some of whom the book had influenced profoundly.In 1951, Rand moved from Los Angeles to New York City, where she gathered a group of these admirers who met at Rand's apartment on weekends to discuss philosophy.The group included future chair of the Federal Reserve Alan Greenspan, a young psychology student named Nathan Blumenthal (later Nathaniel Branden) and his wife Barbara, and Barbara's cousin Leonard Peikoff.Later, Rand began allowing them to read the manuscript drafts of her new novel, Atlas Shrugged.
