New Breaking Dawn Part 1' trailer

Posted: Updated:

PHOENIX – It’s one of the most anticipated movies of the year, “The Twilight Saga: Breaking Dawn Part 1.” It’s hitting theaters in November, but we have the new trailer, which debuted online Tuesday.

This is the second official trailer from Summit Entertainment. At 2:30, it's longer than the original version.

“Breaking Dawn” is the fourth and final book in Stephanie Meyer’s beloved Twilight series. Because the scope of the book is so expansive, filmmakers decided to tell the story in two movies à la Harry Potter.

The movie's tagline -- "Forever is just the beginning" -- speaks volumes about the story.

Picking up where "Eclipse" left off, the movie starts with Bella and Edward’s wedding and then goes on to Bella’s unexpected – and extremely perilous – pregnancy.

Just how dangerous is the baby?

“It’s crushing you from the inside out,” Edward tells Bella even as the mother-to-be's new father-in-law worries that she won't survive the pregnancy.

The trailer gives a glimpse of the birth of Bella and Edward’s daughter Renesmee, nicknamed Nessie.

For the most part, fans have been thrilled with the trailer, loving that like the previous movies, filmmakers stuck to the book.

Kristen Stewart, Robert Pattinson and Taylor Lautner all reprise their roles as the three main characters – Bella (soon-to-be vampire), Edward (vampire) and Jacob (werewolf) -- at the center of the saga.

“Breaking Dawn Part 1," which is not yet rated, opens Nov. 18 and runs about two hours and 15 minutes. “Breaking Dawn Part 2” is due out next year.

The first three movies -- "Twilight," "The Twilight Saga: New Moon" and "The Twilight Saga: Eclipse" -- are all available on DVD.
