-> O.K. no big deal or anything.
I was wondering if anyone knows the production trick used in "Gothika" to create/simulate the girl Ghost's walking pattern. It's, for lack of a better term, sticky. I've played with backward walking reversed, as I am quite certain that was used, but I wonder if anyone knows for certain.
This might be considered a tips/tricks effects question I guess.
While I'm on the subject, I'd also like to hear about some of the other inherently creepy ghost-person effects used in films. The keyed jump-cuts at the end of "The Ring" come to mind.
This subject matter is for general knowledge and not a specific project, so there's no rush for an answer.
