Breaking Dawn movie; Robert Pattinson, Kristen StewartRobert Pattinson and Kristen Stewart push the envelop on drama and suspense in Breaking Dawn, Part 1, judging from a new trailer released today by Summit Entertainment.

The trailer is so new, it was initially only shown on “Access Hollywood,” with Billy Bush drooling over the contents.

But the official trailer (below) has since been posted.

The two-minute,30-second clip is actually an expansion of a 16-second teaser clip that was released last week. It covers most of the same scenes, but with more detail.

It includes a harrowing confrontation between Edward Cullen (Pattinson) and Jacob Black (Taylor Lautner).

Check out Rob and Kristen’s photos; click to enlarge.

Jacob who is backed by his wolf pack issues a chilling threat: “You kill Bella, you kill me,” he snarls.

The clip opens with the wedding scene and shows Bella with her dad, played by Billy Burke.

It cuts to the wedding vows, where Bella utters what will be a fateful premonition… “as long as we both shall live.”

In Bella’s case, that may not be long. Edward spread his seed inside her during their honeymoon and Bella is shocked to find out she is pregnant.

But the baby is half-human, half-vampire, and she is feasting on Bella’s blood in the womb.

There are scenes from the honeymoon, and Dr. Carlisle Cullen’s (Peter Facinelli) dire warning: “The fetus is incompatible with your body.”

If it’s not bad enough to have the wolfpack on you trail, the Cullens must also deal with the Volturi, who are none-too-happy about Bella and Edward’s marriage.

The clip ends with Jacob screaming “Bella! Bella!”

Check it out below. This is the official high definition trailer.
