10 Horror Movie Secrets You Didn’t Know

Remade as a gorier and harsher, but ultimately less interesting torture porn flick from Alexndre Aja in 2006, The Hills Have Eyes is one of future Wes Craven's earlier, nastier horrors.

The intense survival horror pits an all-American nuclear family against, appropriately, an inbred family of monstrous mutants who have been deformed and maddened by exposure to nuclear fallout. It's a bracing satire of Americana which features some intense and horrifying sequences, and it's all the more effective for its slow build up.

For example, the infamous scene wherein the family encounter a tarantula inside their trailer and struggle to fight it off perfectly foreshadows their regression to the state of nature when battling the mountain men. So it must have been planned, storyboarded, and scripted to tie into the film's themes, right?

Actually, the tarantula sequence was entirely unplanned.

The scene was hastily filmed and thrown in during the filmmaking process solely because the filmmakers found the spider on location during filming, picked the giant arachnid off the road, and decided they'd stick it in the movie (and yes, it was safely handled and returned home, animal lovers).
