Pamela Lincoln and Darryl Hickman, who play the young suitors, actually got married on November 28th after the Tingler release on July 29th 1959. They had two children, and divorced on December 8th, 1982.

The earliest film to depict an LSD trip.

The Tingler is a large scale model of velvet worm, also called peripatus. It has its own phylum - Onychophora. It is about half way between and earthworm and an arthropod.

This film is listed among The 100 Most Amusingly Bad Movies Ever Made in Golden Raspberry Award founder John Wilson's book THE OFFICIAL RAZZIE® MOVIE GUIDE.

William Castle toyed with other ideas to frighten audience members, in addition to 'percepto'; among them: rolling bean bags to brush against the legs of audience members, speakers mounted at different areas that would give a 'screech' when the tingler appeared, and possibly even using 'shills' to operate some type of mechanical device to tickle the legs of the audience members; but the only viable way of doing it was by attaching buzzers in select seats to coincide with the appearance of the tingler- 'percepto'.

Clips from Tol'able David (1921) are shown in the cinema.

Co-stars Vincent Price and Judith Evelyn previously starred on stage together in 1941 during the Broadway performance of "Angel Street", based on Patrick Hamilton's play "Gaslight".

In Oct. 1959, Columbia Pictures distributed this film on a double bill with Juke Box Rhythm (1959). Filmed May 18-June 1 1959.

To create the footage of the bright red blood flowing in a black and white film, they simply build a set in shades of black and white so that it would photograph on color film as if were being shot on black and white stock. The flowing bright red "blood" would stand out and create a very dynamic effect. The color footage had to be manually spliced into the black and white release prints. This was in the days before thousands of release prints were needed for a theatrical release.

You may recognize Judith Evelyn, who plays the mute, terrified silent movie theatre owner here - five years earlier, she had played James Stewart's romantically frustrated neighbor "Miss Lonelyhearts" in the Hitchcock classic Rear Window.

This film marked the return of William Castle to this home studio, Columbia Pictures. It also marked the first film for Castle's own production company.

All three actors shown screaming in the film's epilogue are also cast as audience members in the silent movie theater.

This movie was recently show on the Svengoolie show. They claimed it was a digitally restored print.

One of the main possible changes is that the wires used to move the tingler have been erased.

They may have also added a few flashes of color during "Dr. Chapin's" LSD visions in his lab.

William Castle: [gimmick] Whenever blood-curdling screams occurred in the movie, hidden buzzers vibrated the seats. (This feature was called "Percepto.") Shills planted in the audience let out their own screams.

When describing the strength of the Tingler's grip, Vincent Price compared it having his arm in "one of those hydraulic presses". An interesting analogy, since Price had co-stared in "The Fly" the year before (1958) as brother of scientist Andre Delambre (David Hedison) who is killed by having his fly-mutated head and left arm crushed...in a hydraulic press.
