The actor, who plays werewolf Jacob Black in Stephanie Meyer's vampire trilogy, told MTV News that he is looking forward to the film's November release as he is "proud" of the final product.
"I definitely saw it. I didn't see the reaction to it, but I've been really busy. I'm so proud of it. I think the trailer is great. The movie is amazing, and I cannot wait for everyone to see it," he explained.
Lautner also promised that fans will not be disappointed when it comes to Breaking Dawn's more heartfelt scenes, adding: "You are going to face a lot of emotions, definitely.
"You are going to be angry. I guarantee you [that] you will cry multiple times. There's a good mix. It's definitely different than any of the ones before."
Lautner recently confessed that he would feel "crushed" if rejected like his on-screen character Jacob in real life.
