Flipping that car over

At the beginning of this film the Giant Gila Monster attacks a couple in a car and flips their vehicle over and down a ravine - the only problem is, you can clearly see about a dozen people at the top of the screen running away after having completed the job that our Gila Monster was supposed to have accomplished.

I can honestly say that I have never, ever watched this movie in a sober state and enjoyed it. Having said that, the Mushroom song is so rotten that it sounds bad even when you're inebriated. :)
