His character "Riley" is only named on one page of the book for "Eclipse" -- but actor Xavier Samuel graces numerous pages in the new GQ ... and looks really good doin' it.
The Aussie stud, who plays a newborn vamp in the next "Twilight" flick, says his role was greatly expanded for the movie, telling the mag, "We venture into the world of Riley and watch him assembling thisnewborn army. It's more action-packed. And it gives me something moreto do."

The movie opens June 30, the GQ issue is out now.
