Not quite convinced

For decades, J.R.R. Tolkien’s Lord of the Rings trilogy was considered “unfilmable.” The Professor himself doubted that any director could successfully adapt the work. Chief among the challenges? Middle-Earth’s major races come in all shapes and sizes. Men and elves wouldn’t pose a problem, but how could an actor play a four-foot-tall hobbit? Or a dwarf—built like a tank?

To create the illusion of different-sized races for his Rings adaptation, Peter Jackson combined a variety of techniques: green screen compositing, forced perspective, and “little people” as body doubles. At points, he even resorted to the oldest trick in the book: make one actor kneel, or stand another on a box.

Considering all the different tricks used, the composite effect proved remarkably convincing. Most of the time, you forget that Elijah Wood isn’t four feet tall.

But every once in a while, things don’t quite jive. While the characters’ relative heights remain consistent, their girth doesn’t. When you “shrink” actors via green screen composition or forced perspective, they retain their natural proportions. The result is slender, miniaturized humans. But when you film “little people” (as Jackson often does in wide shots), you capture those body double’s stockier proportions. Finally, stand an actor on his knees, and you can dial in the appropriate height, but his head and shoulders don’t scale (compared to the other, “full-size” actors in the scene).

Ideally, Jackson would have selected a single proportion—in both girth and height—then adjusted each technique to maintain that ratio. Perhaps the lead actors could have packed on a few pounds (Elijah Wood always seemed too skinny for a hobbit). Or the film’s digital wizards might have “pinched” the stouter body doubles, slimming them down in post-production.

But given the tools available at the time, it’s understandable that Jackson couldn’t quite “hide the seams.” Fortunately, the technology has improved dramatically in the decade since Rings debuted. Jackson’s Hobbit films feature more convincing character scales.[1] The only hint of trickery? Dialogue delays and eye-line mismatches occasionally make me doubt that Gandalf and the dwarves were filmed together (they weren’t).[2]


  1. One happy side-effect of shooting The Hobbit in 3D? Many of the old techniques (particularly forced-perspective shots) don’t hold up. As a result, Jackson has opted for green screen far more often. Presumably, this allowed his digital compositors to dial in a single, consistent proportion.  ↩

  2. Ian McKellen (who plays Gandalf in both trilogies) found Jackson’s compositing techniques for The Hobbit to be frustrating. Since wizard scale differs from hobbit/dwarf scale, McKellen was forced to work on a smaller Bag End, separated from his fellow cast members. At one point, the actor even shed some tears and protested, “This is not why I became an actor!”  ↩
