Between DOS and BOTFA John Bell (Bain) grew, so that he was nearly the same height as Luke Evans (Bard). So every time you see the two of them in the same scene in the third movie John is behind Luke so he will appear shorter.
Cast of LOTR and THE HOBBIT. Haha the two tallest person of the cast are Thorin and Dwalin, and you'd think they would be the shortest since they play dwarfs. I always think dwarves are normal sized until I see then next to elves.
Nori and Ori. when I was trying to memorize the dwarves, Nori was one of the easiest to remember. His hairstyle looks like a star, so I thought NORthern star= NORi. Hes the coolest looking dwarf in my opiniom.
