usually called a trembler...

Wasn't that a Vincent Price movie?

Wasn't it "The Tingler"?

Yes. I was being a wise-ass.


The essence of fear taking on the form of a lobster / section
of spine, as it is that creature that gives the tingling. Complete
with one on a string, run over the heads of the audience in the
cinema.

That was actually a skeleton, in "House on Haunted Hill", dubbed "Emergo".

Thought a William Castle production, the movie is quite so bad as you might
think. (It's generally considered Herr Schloss's masterpiece.) It's also the
first movie with a reference to LSD.

Rent "Matinee" if you can find it. It's a spoof of Castle and his ilk. The
movie itself is a bit slack and lacks focus, but is worth seeing for John
Goodman's performance as Castle -- and even more for his latest film,
"Mant!", a perfect send-up of '50s sci-fi/horror flicks. (It even has
William Schallert as a libidinous dentist, plus cameos from other veterans
of that era.)
