Suppose Stanley Kubrick was an American film director, screenwriter, and producer. He is frequently cited as one of the greatest filmmakers in cinematic history. His films, which are mostly adaptations of novels or short stories, cover a wide range of genres and are known for their realism, dark humor, unique cinematography, and evocative soundtracks.
Can we infer that "Stanley Kubrick never made a movie based on a book."? Yes, no, or maybe?
