The "Twilight Saga: Breaking Dawn - Part 1" exclusive trailer premiering at Sunday's MTV Movie Awards already has Twilighters losing their minds at the idea of getting a glimpse of Bella and Edward's wedding and much, much more.

Well, it's time to harness that energy, because we have a job for you.

The MTV News crew has seen the trailer already, and while the whole element-of-surprise thing prevents us from actually telling you what's in it, we can promise that it's everything fans want it to be -- and even more.

Now to the part where you come in: When the "Breaking Dawn" trailer premieres at the Movie Awards, airing 9 p.m. ET/PT Sunday on MTV, record your video reaction and upload it to Your.MTV.com. We want to see just how excited you are for the fourth "Twilight" film's arrival November 18. The best, wildest, most enthusiastic videos will even make it on TV on Monday's "The Seven"!

A teaser for the trailer was released last week, and judging by the overwhelming response to that clip, fans are already pretty worked up. Keep that enthusiasm going until Robert Pattinson, Kristen Stewart and Taylor Lautner present the "Breaking Dawn" trailer on Sunday -- and we look forward to seeing just how excited you are during the exclusive sneak peek!
