I could never find out what an interocitor was...

"Stand back... Further, please..."

It's from "This Island Earth", a silly film with a few nice moments. Rex
Reason makes a good alien. ("Mozart? Ah, yes... Your composer.")

In the animated version of "The Coneheads", Beldar communicates with the
home world using an interocitor.

Note how the poster anticipates the "Forbidden Planet" poster.

I've only read part of the original novel, which appeared to be (surprise!)
superior to the movie. The upcoming remake will hopefully be a significant
improvement.
