Anybody here watch The Shinning playing forwards and backwards simultaneously superimposed on the same screen? There's a documentary called Room 237 about this that's up on youtube right now.
This is the what happens when the movie meets in the middle at the "convergence point". The documentary I embedded shows many more examples throughout the movie.
