For those who don't own the EE DVD, the scene where Bombur races past all the other dwarves to get to Beorn's house before them has a story. Steven Hunter (Bombur) realized that the shot they were filming wouldn't show his feet, so he had the costumers help him get his running shoes on. Enabling him to outrace everyone, much to their surprise.
NO YOURE NOT AT ALL!!! Also makes me sad she says this after legolas says "this is not our fight" because they've copied this scene from the two towers when treebeard says "this is not our war" and Merry replies "But you're part of this world! Aren't you?!" And convinces them to fight.
