The final theatrical trailer just released. After watching teaser trailers, fans finally have an over two-minute trailer to satisfy their vampire cravings until the movie is released. [WATCH BELOW]

In the bestselling novel, written by Stephanie Meyers, the Denali, Egyptian, Irish, Amazon, Romanian Coven, and others come to defend the Cullens after Irina reported to the ruling vampire class known as the Volturi that the Cullens (Bella and Edward) created an immortal child. Due to her hatred with Bella (played by Kristen Stewart) because of Bella's relationship with the wolves as well as the unfulfilled revenge of her mate Laurent, she betrayed her sisters and her allies.

The movie also centers on Bella and her new transformation as a vampire, along with her and Edward's (played by Robert Pattinson) half-vampire, half-human child, Renesmee (played by Mackenzie Foy). After the birth of Renesmee, the Cullens gather other vampire clans in order to protect the child from a false allegation that puts the family in front of the Volturi.

Director Bill Condon recently revealed that the movie will run one hour and 56 minutes. Twi-hard fans wish it would be longer!

The movie might turn out to be about four hours if filmmakers included everything that happened, but there's a new twist.

According to Hollywood Life, the final third of the movie will not be one that's in the book. It will be a brand new sequence.

The website reported that the new sequence was "dreamed up by [author] Stephanie Meyer and longtime screenwriter Melissa Rosenberg one night over dinner" that is much different from the book version.

"When I first read the script, I got to that part and was like, 'What?'" Robert Pattinson toldEntertainment Weekly. "And then I had to go back a page."

"It does it a serious justice," said Pattinson.

Stewart agreed. "It's clearly made by someone who really likes [the saga], who really cares," she said. "That's why [director] Bill Condon is perfect. Thank God for him."

Speaking of new things, there is also the new French Coven, which does not exist in the book. Fans should be excited to see some new vamps join the fun.

According to Entertainment Weekly, "Breaking Dawn Part 2" is this season's most anticipated movie on Fandango's annual fall film survey. It got 51 percent of the votes. The movie was also dubbed as the best date night movie.

"Breaking Dawn Part 2" is set to release in theaters Nov. 16, 2012.
