Roman Polanski is particularly sensitive to the "paranoid atmosphere" and has been a great master of the so-called psychoanalytic thriller since 1965 as shown by the movie Repulsion, but mostly visible in his Third-Floor Tenant movie (1976). The film industry can transmit the sense of strangeness of existence admirably due to its ability to bring out details that may appear irrelevant, but that communicate a profound discomfort. The film director also explores the relationship between paranormal and paranoia in the movie Rosemary’s Baby (1968); Stanley Kubrick in his masterpiece The Shining explores this theme as well. The subject of split personality appears in films such as Fight Club (1999) and Lenny (1974), but it takes on a more visionary and "dystopian" nature in Videodrome (1983) and eXistenz (1999) both directed by the Canadian David Cronenberg. Paranoia is accompanied by themes that are dear to science fiction films such as Invasion of the Body Snatchers (1956), 2001: A Space Odyssey (1968), Brazil (1985), Gattaca (1997) and The Matrix (1999). In these movies, the theme of the relationship between dictatorship and freedom is often shadowed.
