Arachnophobia

Trivia: Since spiders really aren't a trainable type of animal, the filmmakers used hairdryers to blow on them, in order to get them to move correctly.

Trivia: Near the start of the film, when Atherton is examining the spider after returning from the valley, several butterflies are seen pinned up in front of him. Several of these are not South American butterflies - the top left one (blue with long tails) is Papilio Ulysses, a species of tropical Australia, and the big green-and-black one near the bottom right is Ornithoptera priamus or O. euphorion. Whether this qualifies as a mistake, I don't know - Atherton is supposed to be an expert, so they may not be the most geographically accurate 'colourful' butterflies to use.

Revealing mistake: When the scientists inject the mouse with poison, they put it in a jar. The, after they place it down you can see someone's hand swap the jar for one containing a dead mouse. You can even hear it. (01:17:58)

Doctor James Atherton: In this first generation, the original male also produced a queen, and together they will construct a primary nest which the queen will guard. But eventually, she will create reproductive offspring of her own. And when that happens, this town is dead... and the next town... and the next town... and the next one, and so on.
