Inquiry of Hollywood penetration of Communism in the film industry. Mr. J. Parnell Thomas gives speech. Eric Johnston of the MPAA speaks. Film is overexposed. Johnston's doublespeak is worth transcription: "We are accused of having Communists and Communist sympathizers in our employ. Undoubtedly there are such persons in Hollywood as you will find elsewhere in America. But we neither shield nor defend them. We want them exposed. We're not responsible for the political or economic ideas of any individual. But we are responsible for what goes on the screen. We guard that with great care. If Communists have attempted to inject their propaganda into the motion picture, they have failed miserably., We will never permit them to succeed."
