'Twilight: Breaking Dawn': Watch the New Trailer

Twilight - Breaking Dawn, Part 1
<p> Controversy has surrounded the film, as <em>Breaking Dawn</em> has a decidedly more mature tone than its predecessors. <strong>Kristen Stewart</strong> has said that the film&#39;s birth scene is much tamer than the novel&#39;s: &quot;It could been shocking and grotesque, because that&#39;s how it was written in the book. I would have loved to have been puking up blood.&quot;</p>
Kristen Stewart, Robert Pattinson and Taylor Lautner return in fourth installment of the "Twilight" saga, which features Bella and Edward's wedding and vampire baby news.

After months of anticipation, the official Breaking Dawn trailer hit the Internet on Sunday afternoon.
