Final answer:
The statement that is NOT true about the film industry in the 1950s is that silent films regained popularity during the decade. The rise of television did impact cinema attendance, the Hays Code predates the 1950s, and Technicolor was introduced before the 1950s.
Step-by-step explanation:
The correct answer to the question of which statement is NOT true about the film industry in the 1950s is: D) Silent films regained popularity during this decade. During the 1950s, several factors significantly impacted the film industry. Option A) The rise of television impacted cinema attendance is true, as television became a common form of at-home entertainment, leading to a decline in movie theater attendance. Option B) The Hays Code, which was introduced to regulate film content, indeed existed, but it was established in 1930, not the 1950s. Option C) The advent of Technicolor did help to revolutionize film coloration, but Technicolor itself was introduced well before the 1950s. As for Option D), silent films did not regain popularity; it was the introduction of "talking pictures" that dominated the motion picture industry since the late 1920s. Therefore, the rise of color films, sound technology, and new genres characterized the evolution of cinema in the 1950s, but the resurgence of silent films was not a trend of this era.
