- SOME BACKGROUND ON WRITER/DIRECTOR/PRODUCER WILLIAM CASTLE
Orphaned at 11, Castle dropped out of high school at 15 to work in the theater. He came to the attention of Columbia Pictures
for his talent for promotion, and was hired. He learned the trade of
filmmaking and became a director, acquiring a reputation for the ability
to churn out competent B-movies quickly and on budget. He eventually struck out on his own, producing and directing thrillers which, despite their low budgets, were effectively promoted with gimmicks, a trademark for which he is best known. He was also the producer for Rosemary's Baby.
- House on Haunted Hill (1959). Filmed in "Emergo". A skeleton attached to wire floated over the audience in the final moments of some showings of the film to parallel the action on screen when a skeleton rises from a vat of acid and pursues the villainous wife of Vincent Price's character.[p. 16] Once word spread about the skeleton, kids enjoyed trying to knock it down with candy boxes, soda cups or other objects at hand.
- The Tingler (1959): Filmed in "Percepto". The title character is a docile creature that attaches itself to the human spinal cord. It is activated by fright, and can only be destroyed by screaming. Castle purchased military surplus air-plane wing de-icers (consisting of vibrating motors) and had a crew travel from theatre to theatre attaching them to the underside of some of the seats (in that era, a movie did not necessarily open on the same night nationwide). In the finale, one of the creatures supposedly gets loose in the movie theatre itself. The buzzers were activated as the film's star, Vincent Price, warned the audience to "scream – scream for your lives!"[p. 17] Some sources incorrectly state the seats were wired to give electrical jolts. Filmmaker and Castle fan John Waters recounted in Spine Tingler! how, as a youngster, he would search for a seat that had been wired in order to enjoy the full effect.
- 13 Ghosts (1960): Filmed in "Illusion-O". Each patron received a handheld ghost viewer/remover. During certain segments of the film, a person could see the ghosts by looking through the red cellophane, or remove the ghosts if they were too frightening by looking through the blue.[p. 18] Without the viewer, the ghosts were somewhat visible. The DVD release included red/blue 3D glasses to replicate the effect.
- Homicidal (1961). There was a "fright break" with a timer overlaid on the film's climax, as the heroine approaches a house harboring a sadistic killer. The audience had 45 seconds to leave with a full refund if they were too frightened to see the remainder of the film. In an early showing, more wily patrons simply sat through the movie a second time and left at the break to get their money back; to prevent this in future, Castle had different color tickets printed for each showing.[pp. 18–19] About 1% of patrons still demanded refunds. John Waters described Castle's response:
"William Castle simply went nuts. He came up with 'Coward's Corner,' a yellow cardboard booth, manned by a bewildered theater employee in the lobby. When the Fright Break was announced, and you found that you couldn't take it anymore, you had to leave your seat and, in front of the entire audience, follow yellow footsteps up the aisle, bathed in a yellow light. Before you reached Coward's Corner, you crossed yellow lines with the stenciled message: 'Cowards Keep Walking.' You passed a nurse (in a yellow uniform?...I wonder), who would offer a blood-pressure test. All the while a recording was blaring, "'Watch the chicken! Watch him shiver in Coward's Corner'!" As the audience howled, you had to go through one final indignity – at Coward's Corner you were forced to sign a yellow card stating, 'I am a bona fide coward.'"[p. 19]
- In a trailer for the film, Castle explained the use of the Coward's Certificate and admonished the viewer to not reveal the ending to friends "or they will kill you. If they don't, I will."
- Mr. Sardonicus (1961). The audience could vote on the villain's fate in a "punishment poll" during the climax – Castle appeared on screen to explain two options. Each member of the audience was given a card with a glow-in-the-dark thumb they could hold up or down to decide if Mr. Sardonicus would be cured or died. Supposedly no audience ever chose mercy, so the alternate ending was never screened.[p. 20] Though Castle claimed in his autobiography that the merciful version was shot and shown occasionally, many suspect otherwise. In the drive-in version, drivers were asked to flash their car headlights to choose.
- Zotz! (1962). Each patron was given a "Magic" (gold colored, plastic, glow-in-the-dark) coin.[p. 178]
- 13 Frightened Girls (1963). Castle launched a publicized worldwide casting hunt for the prettiest girls from 13 different countries.[p. 20] He filmed slightly different versions, highlighting each girl for the release in her country.
- Strait-Jacket (1964). Advised by his financial backers to eliminate gimmicks, Castle hired Joan Crawford to star and sent her on a promotional tour to theatres. At the last minute, Castle had cardboard axes made and handed out to patrons.[p. 20]
- I Saw What You Did (1965). The film was initially promoted using giant plastic telephones, but after a rash of prank phone calls and complaints, the telephone company refused Castle permission to use them or mention telephones. So he turned the back rows of theatres into "Shock Sections". Seat belts were installed to keep patrons from being jolted from their chairs in fright.[p. 21]
- Bug (1975). Castle advertised a million-dollar life insurance policy for the film's star, "Hercules" the cockroach.[p. 255]
Rosemary's BabyAccording to Spine Tingler! The William Castle Story, he mortgaged his home (again) and obtained the movie rights to the Ira Levin novel before it was published, hoping to finally direct a prestigious A movie himself. He made a deal with Paramount Pictures, which however insisted on hiring director Roman Polanski. Castle had to settle for producing the film. He had a cameo, playing the grey-haired man standing outside the phone booth where Rosemary, played by Mia Farrow, is attempting to get in touch with the obstetrician.
Castle was unable to build on the film's success. He suffered kidney failure soon after its release. By the time he recovered, all momentum was lost, and he went back to making B movies. His most significant acting role was also his last -- as the director of the doomed "Waterloo" epic in The Day of the Locust in 1975.
