We probably should have noticed this before.

I remember as a kid thinking that after I saw a movie trailer in the theatres, I had already seen the best parts. While child me may still be right, someone has at least proven that all action movie trailers at the very least follow the exact same formula.

Most of the recent comic-book / cartoons from your childhood / movies already made in the 80's are featured in one video that seems like it's only a little bit longer than an actual trailer.
