How Weta Workshop Crafted The Best Parts Of Ghost In The Shell

This year's Ghost In The Shell adaptation was a visually stunning movie — helped in no small part by the gorgeous practical effects, props and costumes built by New Zealand's Weta Workshop. In fact, far more of the film's beautiful visuals were built physically than most people would expect. We went to Weta to find out what went into building the world of Ghost In The Shell— and what it's like when your painstakingly crafted work is hidden behind layers of digital effects.

It may surprise some people (myself included) to know that Ghost In The Shell used more practical effects than most other films of its kind do. With Weta Workshop on the job, you'd hope they'd make use of that talent. You may have seen Adam Savage's feature on the animatronic robot geisha heads, or the fully silicone thermoptic suit, but there were many other scenes that required building huge props and complicated animatronics rigs, not to mention the prosthetics that created the film's many minor characters.

Weta Workshop's Head of Manufacture, Rob Gillies, said that it was often a case of convincing Director Rupert Sanders of the case for creating film elements physically — especially in a film landscape where digital is the norm.

Fine Art: The Incredible Art Of The Ghost In The Shell Movie

Say what you will about the new Ghost in the Shell as a movie, one thing I think we can all agree on is that it looks absolutely stunning. So let's check out some of the concept art work that went into creating the film's look.

One scene that was shot largely in camera, though it didn't look it, was the 'shelling sequence' that opened the film. While the construction of the ScaJo 'shell' looked like a lot of slick special effects, it was mostly composed of Weta's handiwork — from a full skeleton to a sleek white mannequin and the pool full of viscous white fluid it emerges from. While the robot geisha animatronic got a lot of attention into the lead up to the film, the shelling sequence also required a lot of complex animatronics, like a rig to slide the 'brain' inside the body, and another that had the 'petals' of the skull closing over.

Unlike films like The Lord Of The Rings that were the result of close collaborations between Weta Workshop and Weta Digital however, Ghost In The Shell was handed over to an outside company for its digital effects. This meant that the original creators had little idea how their work would actually look until they saw the finished product. A lot of the original practical effects were layered over with generous amounts of CGI — pieces such as the thermoptic suit were almost lost beneath the digital constructions that ended up on the screen.

Of course these pieces are always designed to coexist with their digital counterparts, but when you see the kind of incredible work and care that gets put into the practical effects it's easy to wish they got a little more space to show off.

I felt this especially with the stunning thermoptic suit, as that was one piece that used some of the most cutting edge technology used in practical effects for film.

We talked to Weta costumer Flo Foxworthy about the suit she took the lead on, and even got to see it up close. It used a material that Weta was already incredibly familiar with, silicone, but used it in a way that was completely new to them — and to the whole industry, in fact, as it ended up being the first of its kind in the world. One of the most interesting new techniques used on the thermoptic suit involved CNC milling machines — usually used to cut designs into hard materials like metal or wood — which etched the fine details onto the plasticine model that the mould was later taken from.

Techniques like 3D printing are constantly expanding what's possible in the realm of practical effects, and this was especially evident in some of the work done on Ghost in the Shell. Print quality is constantly improving, and new filament materials mean more and more different effects are possible through 3D printing. These days Weta uses 3D printers for everything from mocking up quick prototypes to creating finished pieces.

At Least Ghost In The Shell's Geisha Robots Look Great

The action in the latest Ghost in the Shell trailers have a bit of that "this could be really, really terrible" quality, but hot damn they nailed the geisha robots.

One interesting application mentioned by makeup artist Jason Docherty was the potential to use 3D printing to duplicate moulds for prosthetic makeup pieces which, so far, have been almost impossible to exactly replicate. While these moulds are usually quite durable and last a long time, duplicated would come in handy when making a prosthetic-heavy film like The Hobbit. When each dwarf actor required a new facial prosthetic made for each day of shooting, the ability to run them in multiple moulds at once could have been invaluable.

Of course among all these high-tech processes, sometimes it's the simplest things that can present a challenge — one of the hardest tasks Gillies' team encountered working on Ghost in the Shell was just attempting to paint the perfect circles on the geisha's masks. Go figure.

    Its a damn shame it didnt succeed. She always seems to get screwed and although I didnt like what they did with the character in comparison with the original that didnt stop me enjoying the film.

    I've seen a few really cool behind the scenes videos on this, but I get the impression a lot just got replaced with CGI for the final film.
    Even some of the stuff that they brag about being practical, still isn't what we saw on the screen. So they filmed all this practical stuff of her being built, but almost all of that scene ended up being cgi in the film.

    its a shame it didn't deliver on the story or character front. Nice to look at and generic actions scenes but not compelling or well written.
