To get in the spirit of Halloween, here are a couple videos.
First, the directors of a commercial for a well known (multi-national) car company were astonished when viewing their recently created advertisement as there appeared to be a ghost car following the real car!!
Personally I find this piece of footage amazing, you can definitely see an ominous black shadow following the car as it appears from behind the second set of trees.
You have to watch the clip very closely......
Next we have an adaptation of one of the scarier scenes in The Exorcist.
