The farm is run by a strange man named Greely, who tells them that the gasoline truck was supposed to arrive the previous day, but since it didn't, he expects it there any minute.
He takes them out to the yard and shows them his "zoo", which includes ordinary animals like turtles, rattlesnakes, coyotes, and a bobcat.
Greely leaves the cave, laughing as Leela discovers that Thomas is inside the cell as well, badly wounded but alive.
A reluctant Wayne and Leela follow and discover a prehistoric, aquatic dinosaur coming out of a spring, which Greely apparently feeds live victims to.
Norman urges Leela to go for the gun, but Greely tells him that it won't do him any good, and leaves.
Norman rushes down and gets the pistol, but suddenly the monster appears out of the water as Leela and Wayne warn him.
Bella arrives and reveals that she is not Greely's housekeeper; he kidnapped her and abused her until her will was broken and she agreed to do whatever he told her to do to avoid being fed to the creature.
Wayne remembers that he has some dynamite in his car, and he asks Bella to sneak upstairs and bring back some of it.
In 1963, John Tomerlin was reportedly adapting the Richard Matheson story "Being" for American International Pictures under the title It's Alive.
Nine days later we had cut, scored and printed the film and delivered it to AlP, who made a five o'clock deadline for a package to one of their stations.
[8] Kirk recalled "I worked very hard on It's Alive, trying to be believable about being pursued by some kind of monster, and it turned out the bastard wouldn't spend a nickel on special effects.
Instead, he got ihe guy who was the stand-in—ihe allpurpose stand-in—to put on a scuba suit with cut-out ping-pong balls for cyes, and that was the monster!
[10] The monster suit for the dinosaur was reused from one of Buchanan's older films, Creature of Destruction.
[12] A review in DVD Talk reported that the film features "endless footage of a couple driving" and that "[i]f you disregard the kill scenes, the laughable rubber monster suit, the clunky photography, the plodding pace, and ample padding, It's Alive!
