In May of 1947, the House Un-american Activities Committee (HUAC) held a series of closed-door hearings to investigate communist influence in Hollywood, which led to the famous Hollywood Ten investigation. This document was created on September 21, 1948, almost a year after the Hollywood Ten investigation began. The document illustrates the committee’s belief that communist persuasion continued to infiltrate the industry, thus continued monitoring of Hollywood was necessary. It also suggests that the Hollywood Ten investigation did not prevent the creation of “un-American” movies.
