Teasers: Super 8

This teaser is almost pitch perfect because it does what every teaser trailer should do, intrigue you. It's a teaser that raises so many questions that you can't help but want to know more. Like why is it called Super 8? Will it have something to do with Super 8 cameras? Why is someone driving a truck directly into a train? Was that person purposely trying to derail it so the alien inside could be set free? Why would that person want to free the alien? Is it even an alien? Why does J.J. Abrams rule so much? All I know is that I'm sure all these questions will be answered and more when Super 8 comes out next summer (except for maybe that last one.)
