 The human-sized characters (Gandalf, Aragorn, Boromir and Legolas) were filmed in a second take, and the two shots were composited at different scales to make one image, making the initial Dwarf/Hobbit character shot seem smaller.An unintended advantage of not creating a third scale for Dwarves is that in a scene in which only Dwarves and Hobbits interact, no scale doubles are needed.Large and small scale doubles were used in many other scenes, while entire duplicates of certain sets (including Bag End in Hobbiton) were built at two different scales so that the characters would appear to be the appropriate sizes.
