Super 8

At the end of the trailer, when the door is been blown out of the train you'll see a lens of a super-8-camera. When you play that part frame by frame :

- 1st : you see a face of someone that looks scared.
- 2nd : After that you'll see the line "Scariest Thing I Ever Saw" written on the film of that same super-8-camera.

There's a rumor that this movie is the sequel of "Cloverfield" , also a movie by JJ Abrams.

I wonder how the final movie will be...
