Yes Nimoy was in about 5 seconds as an Air Force clerk, he tore off a teletype sheet and handed it to, I can’t remember who, lol.
Love these type movies.
Them, Deadly Mantis, Beginning of the End (grasshoppers, Peter Graves), Tarantula, The Black Scorpion, It Came From Beneath the Sea (octopus), Beast from 20,000 Fathoms (dinosaur,w/King Donovan also in Invasion of The Body Snatchers, and Cecil Kellaway cousin, of Edmund Gwenn)
They don’t make movies like they used to!
