In the book, Jacob describes his imprinting as feeling everything in his life - his love for Bella, his family, and the loyalty to his pack- sever away, and then bound by millions of steel cables to the center of the universe -- Renesmee.	In the movie, he experiences his imprinting through a flashforward vision of Renesmee's future appearances and himself as a wolf.
A fight never erupts between the Cullens and the pack, though it was initially planned.	A fight erupts behind the Cullen house after Renesmee was born, until Jacob emerges to tell the wolves that he has imprinted on her.

In the movie, Sam and his pack descend on the house, attack the Cullens, and a fight ensues as they try to get to Renesmee. Jacob then phases to intervene, and Edward tells everyone about the imprinting after reading Jacob's thoughts. Once Sam hears this, the fighting stops, he and his pack retreat, and a truce is back in effect. Edward explains to the rest of the Cullens that this is "the most absolute of all the pack's laws" and that it means the hostility is over.
Bella describes the transformation process as painful flames that spreads throughout her whole body and burns her for several days while her transformation goes on. When it nears its completion, the flames begin to reduce, but at the same time, her heart beats faster, more violently to fight against the venom that is killing it. Eventually, it beats as strongly and painfully as a helicopter's propeller and thuds one last time before it stops.	In the movie, her transformation begins with her experiencing the painful process, but otherwise it is seen going smoothly and painlessly. Her body heals itself, and then her memories of the past flash in front of her as every drop of her blood converts. When the final drop turns white, her transformation is complete.
The Volturi do not appear until near the end of the book.	The Volturi make a post-credits appearance.
Bella tells the Cullens and Jacob her baby names a few days before she gives birth.	It is right after Bella reveals her name decisions when she drops her cup of blood and goes into labor.
Bella's going away ensemble was described as deep blue.	Bella left the wedding reception wearing a cream colored dress with a black bow at the waist.
