The Abducted actor explained that he can "relate" to Jacob's storyline in the upcoming adaptation of Breaking Dawn, to be released in November.
"I can relate to Jacob's feelings in Breaking Dawn," he told Seventeen magazine. "When he gets the invitation to the wedding, he doesn't handle it very well.
"I don't think I would either. If I were in love with a girl and she told me she was marrying somebody else, [it] would crush me. That's what it does. It destroys Jacob."
Lautner recently said that his Twilight co-star Kristen Stewart will make a "dark and edgy" Snow White in Snow White & the Huntsman.
