Recreating the Book of the Dead Trailer Distortion effect

Hello,

I was trying to recreate the Book of the Dead distortion effect that is at the end of the trailer here:

I am assuming it some kind of post effect that effects objects in a certain depth pass.

Any tips or ideas would be much appreciated!

Thanks in advance!

Edit:

I found this article that seems like the closest to doing what I'm trying to attempt:

Is there a way to do this without using a second camera?
