Twilight Examiner reports:
Emmett’s character will become more relevant, as it happens in the book, and opened a little door that will allow us to see how Emmett is.
While "Emmett" had a few vital scenes in Twilight (most particularly, guarding "Edward" and "Bella" on the truck while they fled "James"), his part in The Twilight Saga: New Moon was very small. In Eclipse, though, we got to see a bit more of the character in action (as he has an important showdown with "Paul" at the La Push line - which, thankfully, we got to actually see in the film version of the story). Still, "Emmett," unlike "Rosalie," "Jasper," and "Carlisle," didn't get a full-on backstory in the books (though there was an outtake on Stephenie Meyer's website from Twilight).
So, it should be interesting to see Lutz get some prominent screen-time in Breaking Dawn. There are two scenes which come to mind from Breaking Dawn that'll really make Lutz's portrayal pop - the "arm-wrestling sequence" and all his "Honeymoon talk" with "Edward."
Lutz also talked about his excitement over Bill Condon directing the film.
I love his work, I’ve seen all his movies and I really look forward to meeting him and the great team working with him, I’m really looking forward to working with him.
