Scientist discovers a parasite that feeds on human fear--it's the thing that causes your spine to tingle when frightened. People can stop its habit of breaking your spine by screaming. But what happens if someone can't scream?
William Castle's best film, both in terms of actual cinema and marketing (Percepto, where certain theater seats were wired to simulate the Tingler). A very interesting film, full of wild ideas courtesy of Robb White's script, as well as some very good performances; not only from Price (of course), but especially the laconic Philip Coolidge, probably the best character actor of the 1950s. And this is probably the first film to use LSD in the plot!
And remember. . .the Tingler is loose in this theater! Scream! Scream for your lives!!
