50. 'Arachnophobia' (1990)

Spiders. John Goodman with a blowtorch. Who's scarier? I'm sure we could ask Roseanne, but that's the subject of a much more frightening movie. Anyway, as anyone who has er, squashed a spider can attest, things with eight legs are creepy. Gross. Big ones that fly through the air when provoked? Even worse.
