John Rhys-Davis visited the set and the first thing he said was, "Daddy" to Gloin. Then he promptly began to tell them of the horrors of being a dwarf (i.e: running up a hill in full costume). Gotta love this man!
(Click!) Found on Tumblr: "I just spotted this. Just look at how Bilbo seems to be gripping Bofur’s elbow. This is so endearing, it’s unreal. What this shows is how much trust Bilbo has in Bofur. Perhaps not enough to freak out and tackle hug him for safety, but enough for him to seek a little comfort from having the lovely dwarf at his side..." THAT IS BEAUTIFUL.
