Lautner, who plays a werewolf in the hit vampire film series, reveals the entire cast and crew, including his famously emotionally-guarded co-star Stewart, became teary eyed as production drew to a close on the final installment of the franchise.
And the actor admits he's still struggling to come to terms with the end of The Twilight Saga.
He says, "We've literally been filming these movies for the past four years. It's strange to know I'm not going back, that I'm not going to be Jacob Black anymore...
"On the last day it did get emotional. To be honest (people cried). I was pretty upset myself but I think the biggest surprise was Kristen."
The Twilight Saga: Breaking Dawn - Part 1 will hit cinemas later this year (11), while Part 2 will be released in 2012.
