Continuity mistake: After Renesmee's birth, there are two smudges of blood on Edward's right cheek. While Edward works to transform Bella, the blood spots appear and disappear between shots.
Revealing mistake: After Bella gets married and Jacob is angry because he thinks Edward will kill her, Sam tells the pack to leave. When the pack enters the woods, they jump down into what appears to be some sort of pit. You can see blue lights, slightly illuminating the pit area in the woods that Jacob and the pack jump down in.

Continuity mistake: At the end, just after Renesmee's birth, the blood pattern on the front of Edward's blue shirt changes within minutes from being one solid red mass to more mottled.
Continuity mistake: When Jacob packs meets with Sam's pack to distract them so the Cullen's can hunt all of Sam's pack except for Sam is talking to all of Jacobs pack. Two wolves which appear to be Quill and Jared get up and chase some of the Cullens which doesn't make any sense cause all the wolves were meeting with Jacob except Sam. (01:33:11 - 01:34:35)
Answer: Imprinting is an involuntary mechanism. The shape-shifter can't voluntarily imprint on anybody. Jacob tried to imprint on Bella but was unable to do so and began going around looking for other girls to imprint on but, is unable to do it of his own free will.
On the flip side, Sam Ulee was in love with Leah Clearwater, but then he involuntarily imprinted on Emily, dumping Leah and breaking her heart.
