Nearly 1,000 fans camped out in a 'tent city' set up near the Nokia Theater in downtown Los Angeles over the weekend. Many arrived as early as last Thursday.
As they walked the red carpet in front of the Nokia Theater, the stars of the film spent a lot of time thanking the fans who are so committed to the franchise.
"It surprises me that we travel the world and the passion and the fans are the same, worldwide," said actor Taylor Lautner, who plays the werewolf "Jacob" in the Twilight films.
Summit Entertainment held several events for fans over the weekend.
There was a screening of the first "Twilight" movie for fans Thursday night.
"New Moon," the second film in the franchise, was screened on Friday night, and "Eclipse" was shown on Saturday night.
On Saturday, fans were also treated to an outdoor concert featuring performances from several bands featured on the "Breaking Dawn Part 1" soundtrack, including Mia Maestro, Imperial Mammoth, Sleeping At Last and Aqualung & Lucy Schwartz.
Various cast members came out to say thank you to the fans and treat them to breakfast on Sunday morning, including Peter Facinelli, who plays Dr. Carlisle Cullen, the adoptive father of Robert Pattinson's popular vampire character, Edward.
"We show them our love and support, so that's why it's important for us," Facinelli told KTLA.
"You meet the actors who play your favorite characters, you get autographs... My sister and I have done it for the last three years now," one excited fan said.
"Amazing... simply amazing," Marsha Pouly, who came from St. Louis for the premiere, said. "Everybody's gone all out for us."
More than 1,000 shows have already sold out on Fandango.
"I love the books so much and they mean a lot to me," said fan Michelle Mota, who came from her home in Las Vegas to attend the premiere.
The movie opens in theaters nationwide on Friday, Nov. 18.
