 This was achieved by simply casting tall actors to play Dwarves, who thus seem proportionately taller than the average-height Hobbit actors, without the need for camera tricks or digital compositing.Thus Gimli rarely interacts with Men and Elves within the same camera frame, or when he does, Gimli is actually played by a shorter stunt double seen from behind.In contrast, because Dwarves and Hobbits are in the same size scale, Gimli interacts freely with the Hobbit characters within the same camera frame.
