  • INTERVIEW with ROBERT BLOCH - 1 - by Jean-Marc Lofficier
    INTERVIEW WITH ROBERT BLOCH - 1 - By Jean-Marc Lofficier INTERVIEW WITH ROBERT BLOCH Randy and Jean-Marc Lofficier RL: Who do you consider to be at the root of your inspiration for your writing of terror and horror fiction? RB: Well, I spent eleven years in an advertising agency! Actually, as a child I was interested in reading that sort of thing. But, I was more interested, and I think most imaginative children are, in the mysteries of death, age and cruelty. Why do these things happen? Why do people do these things to one another? An innocent child believes in the protection and security of his daddy and mama, his friends and his safe home environment. Then to read and learn about these things is a great shock. I've done a good deal of talking with many other contemporary writers of this sort of fiction, people like Stephen King, Peter Straub, Richard Matheson and half-a- dozen others. They all had the same experience; they all feel this was their motivation. Some kids don't think about these things particularly, but I did. Particularly when I was hiding under the bed or in the closet after seeing something like Lon Chaney in The Phantom of the Opera for the first time at the age of 8 or 9. I decided, as I guess most of these people did, if you can't lick ‘em, join ‘em. So, I learned the method of what it is that terrifies other people as well. Yet, I tried to do it in a way that is safe.

Obsessions, paranoia, wilful acts of self-destruction surround us constantly. Though we age we still hear the cries of those for whom the attraction to mournful chaos is monumental.” Because of this common contemporary feeling, our age can be called, what Teresa Brennan has termed “the age of paranoia” (Brennan 20). Everything we experience seems to belong to a global world of technological information that gives us access to instantaneous “contact”, giving also the feeling that we live in a reality that does not exist, or only exists in our minds as a kind of imaginary construct, leading to what Freud called a fixation in a narcissistic state of being.

  • The Birth of Haptic Cinema
    The Birth of Haptic Cinema An Interactive Qualifying Project Submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Bachelor of Science by Panhavuth Lau Jordan Stoessel Date: May 21, 2020 Advisor: Brian Moriarty IMGD Professor of Practice Abstract This project examines the history of The Tingler (1959), the first motion picture to incorporate haptic (tactile) sensations. It surveys the career of its director, William Castle, a legendary Hollywood huckster famous for his use of gimmicks to attract audiences to his low- budget horror films. Our particular focus is Percepto!, the simple but effective gimmick created for The Tingler to deliver physical “shocks” to viewers. The operation, deployment and promotion of Percepto! are explored in detail, based on recently-discovered documents provided to exhibitors by Columbia Pictures, the film’s distributor. We conclude with a proposal for a method of recreating Percepto! for contemporary audiences using Web technologies and smartphones. i Contents Abstract .......................................................................................................................................... i Contents ........................................................................................................................................ ii 1.

  • The Psychology of Satan Jennifer Putnam This Paper Was Written for Dr
    The Psychology of Satan Jennifer Putnam This paper was written for Dr. Thomas! Milton course. It was presented at the 2009 Sigma Tau Delta International Convention. John Milton!s Satan is a psychologically complex character. Satan has qualities which make him a brilliant leader, but which also cause him great pain. He is a militant ruler with powerful speeches, and a cunning deceiver with rich disguises. The actions Satan takes, however, cause him great an- guish. It is through his soliloquies that Satan takes off his mask and reveals the troubled person he really is. John Milton in Paradise Lost portrays Satan as a proud, passionately manipulative, and complex character that endures an internal conflict from which he cannot escape. Though Milton begins his masterpiece in medias res, we must start from the beginning with Satan as the angel Lucifer. Lucifer enjoys his high stature in Heaven, until the Son is anointed instead of him, and he becomes jeal- ous. It is then that Lucifer draws emotionally away from God and Heaven. James Holley Hanford and James Taaffe show the results of this jealousy by commenting, “Following God!s announcement of the Son!s elevation, Satan initially defected from the angelic forces” (172). His defection is a result of be- ing too proud of being a servant, which leads to anger and thus, his rebellion. Royland Frye points out the irony of Satan!s refusal to become a slave in that Satan actually becomes a slave to his emotions. Frye says, “As a result of his choice, he becomes a slave to what would, psychologically, be called an "ego- deal,! an identification of the self with an impossible image,” (35).

  • Psycho by Charles Taylor “The a List: the National Society of Film Critics’ 100 Essential Films,” 2002
    Psycho By Charles Taylor “The A List: The National Society of Film Critics’ 100 Essential Films,” 2002 Reprinted by permission of the author The impact of Alfred Hitchcock’s “Psycho” owes so much to its two big surprises that when the film opened in 1960 Hitchcock not only refused to allow press screenings but had theaters hire Pinkerton security guards to prevent latecomers from entering the theater once the picture had started. He wanted to keep the people who hadn’t bought tickets from finding out that Janet Leigh’s Marion Crane is stabbed to death in the shower only forty-five minutes into the movie, and that the murderer is Antho- ny Perkins’s Norma Bates, who has succumbed to the personality of the mother he murdered years before. In many ways, “Psycho” seems like a death knell for the studio system that would lumber on for a few more years before collapsing later in the decade under the weight of filmmakers and audiences sick of the old stultified formu- Alfred Hitchcock holding a clapper on the set of “Psycho.” las.

  • Film Music: Hitchcock's Psycho Transcript
    Film Music: Hitchcock's Psycho Transcript Date: Wednesday, 15 October 2008 - 12:00AM FILM MUSIC: HITCHCOCK'S PSYCHO Professor Roger Parker At the end of the last lecture, my first in this series about film music, we were in the early 1930s, in the company of an exuberantly screaming Fay Wray as she heralded the appearance of her exceptionally tall and exceptionally dark leading man. The musical accompaniment was an equally exuberant symphonic score by Max Steiner, one of the great composers of the period. As I said then, there are plenty of ways in whichKing Kong now looks dated in both visual and musical terms; but there are equally striking ways in which Steiner's score marks the appearance of a set of codes about how music was to interact with the visual element of films: codes that to some extent remain with us to this very day. One of the most obvious of these codes was in Steiner's use of what we in the music trade call leitmotifs: prominent themes that become attached to aspects of the unfolding drama and that then recur, sometimes with significant development, when those aspects recur in the narrative. And so, in King Kong, the gentle string theme that accompanied the heroine's onboard love scene comes back, played by the full orchestra and horribly distorted, as the camera settles on her, struggling to escape becoming the next sacrificial victim to the monster of Skull Island. This was, of course, an old trick borrowed (as were so many film-music devices) from opera: the obvious point of reference is the leitmotif system elaborated at huge length in Wagner's operas, but the technique goes back a good deal further.

  • PSYCHO NOTES 1. the Mother, Norma Bates, Is a Classic Super-Ego Character, Internalized by Norman. the Tension in the Film Comes
    PSYCHO NOTES 1. The Mother, Norma Bates, is a classic super-ego character, internalized by Norman. The tension in the film comes from not knowing that she is actually dead and mummified. She is the ‘thing that refuses to die’ in the sense that Norman’s internalization of her keeps her alive and her body is not buried but treated as alive. 2. The house is a classic ‘uncanny’ house: Victorian, high on a hill, ‘empty’. The house contains the secret, and getting into the house stages the attempts to uncover the truth. 3. The theme of voyeurism is a perversion that is itself perverted. Instead of leading to sexual pleasure, Norman adopts the persona of his mother to kill Marion Crane. His pleasure is sadistic rather than sexual or, rather, he derives sexual pleasure from the stabbing — as God seems to do in the case of Sta. Theresa. 4. The drain and the eye dominate the shower scene; this is the Real! The camera wanders away, pausing to look at objects in the room, and then drifts out the window toward the house. 5. The role of the voice is key. Normal ventriloquizes his mother’s voice, staging conversations that the audience takes to be actual until they discover the mother’s corpse. Is there, like in Vertigo, a phrase? Possibly the shift in the role of the acousmatic voice is an indicator that Psycho is a different kind of ‘discourse’. 6. What is the meaning of the taxidermy theme, apart from the role it plays in explaining Norman’s anxiety to preserve the mother’s body.
