![]() ![]() The real refinements came in movie three, where all the extra skin detail, the wrinkling and everything, sort of just culminated at that point. So we started working on all these systems in 1999, and we really didn’t need them working 100 percent until 2002, really, when we really had to get The Two Towers out and you really saw Gollum for the first time. Yeah, so you didn’t really need to have that much detail in him for that one. I mean, the good thing was - the great thing is - Gollum was in film one, like what, four times? Just little hints of him in the background. ![]() ![]() So as parts were finished, we were able to slowly put them all back together and build this. We broke up the ideas, the different bits of code, into several different people, so one person was working on volume-preserving parts of the muscle, another was working on the attachment, another was working on the connections of the skeleton, all the different implementation parts. So instead of the skin getting pulled around by the skeleton underneath, they were actually getting pushed around by the muscles performing and moving underneath the skin. The difference with this system is, the muscles underneath were actually moving and pushing the skin around. So the bones underneath drive the skin, and they’re given different weights so they slide around based on how much that bone underneath is moving … So it’s driven by a point inside of the skin. A basic skinning is, you take points on the skin of the character, or the geometry of the character, and attach it to the bones underneath. So as Gollum bends and moves around, the muscles would flex and move like real muscles would, and allow Gollum to get skinned through this muscle system, which was a completely different way of doing things at the time.Įveryone has something slightly different, but it all is based on skinning. When we did Gollum, I was head of the creatures department, and we were writing our own volume-preserving muscle system that allowed us to basically take a skeleton, where we actually built the bones and everything for Gollum, and then put the muscles onto the skeleton and attached them at the proper points. So it’s lots of different areas of technology within Weta that put all that together. ![]() Well, the Subsurface technology itself, was actually Ken McGaugh and Joe Letteri who did the majority of the work for that, and they basically took a concept paper that had been written and implemented the math and the information in the paper into a shader-based system, so that we could put it onto the skin of Gollum. What was the process of creating that technology like? It’s different implementations of it, but it’s the same basic concept that was back on Gollum. It spreads the light as it goes through the surface so you get that skin-like feel. It’s basically like, if you light a wax candle, you see the diffusion of the light through it. Yeah, it’s called Subsurface and we actually got an Oscar for that technology. That was something that had never been done before. I remember reading that the reflection of light on and under Gollum’s skin and the way you could see his veins was one of the biggest innovations that you guys pioneered. Because he was so skinny, you saw all of the muscles moving under his skin. And because we were inventing technology as we were doing it, it was a huge challenge. Up to that point, you’d seen a lot of CG creatures, but none to the level of Gollum, where the detail him an actor on screen, rather than just a scary monster, which is what a lot of the CG creatures up to that point had been. The article has been updated with new information and the formatting has been adjusted to meet current CBR guidelines.Eric Saindon: When we did Gollum, no one had really done a CG creature mixed with live action that you were supposed to believe was just a creature in the scene. Peter Jackson shed more light on him for new fans in the opening sequence of The Return of the King, which recounts how Smeagol found - and was enslaved by - the One Ring. Updated on Maby Robert Vaux: Tolkien's work discusses Smeagol's origins, but they're shrouded in mystery in the text of The Lord of the Rings itself. So, the question of how old Gollum is and how long he was in possession of the Ring is an interesting one to delve into. Time and characters' ages can often feel like a complex matter in the world of Middle Earth, with Aragorn being 86 at the time of the main story due to the Elvish blood in his veins and Hobbits not coming of age until they're 33. Not least of which is how old Gollum actually is. But due to his mysterious nature, it does raise a lot of questions. The main thing most audiences know about the small creature is his eternal obsession with The One Ring that he bore for so long. ![]()
