Here are sounds used in movies that you might say that they're... WEIRD!
Remember when the spider in ARACHNOFOBIA is stepped by one of the actors? As a matter of fact, they do step the spider... It has a hole on the shoe of the actor to protect it! The sound your hear is potatoes chips being crushed!
Remember the anoing sound that the huge T-rex did in JURASSIC PARK? That sound came from a baby elephant!
