Rand extended her involvement with free-market and anti-communist activism while working in Hollywood. She became involved with the Motion Picture Alliance for the Preservation of American Ideals, a Hollywood anti-Communist group, and wrote articles on the group's behalf. She also joined the anti-Communist American Writers Association. A visit by Isabel Paterson to meet with Rand's California associates led to a final falling out between the two when Paterson made comments, which Rand considered rude, to valued political allies. In 1947, during the Second Red Scare, Rand testified as a "friendly witness" before the United States House Un-American Activities Committee. Her testimony described the disparity between her personal experiences in the Soviet Union and the portrayal of it in the 1944 film "Song of Russia". Rand argued that the film grossly misrepresented conditions in the Soviet Union, portraying life there as much better and happier than it actually was. She wanted to also criticize the lauded 1946 film "The Best Years of Our Lives" for what she interpreted as its negative presentation of the business world, but she was not allowed to testify about it. When asked after the hearings about her feelings on the effectiveness of the investigations, Rand described the process as "futile".
