There was also “Bug,” the final work by the producer William Castle, best known for “Rosemary’s Baby.”

The plot: Incendiary cockroaches released from underground by an earthquake are made resistant to life on the surface by a mad scientist and wreak havoc in California.

The roaches eventually develop superintelligent abilities and, of course, become carnivorous.

A review in The Times described the film as “decidedly poisonous” and “cruel.” It urged parents not to let their children see it.

Coincidentally, the director of “Bug,” Jeannot Szwarc, went on to direct “Jaws 2.”
