Celebrate the VFX of the now 25-year-old movie.
Films such as Fantastic Voyage, Inner Space, Willow, Honey, I Shrunk the Kids, Hook, The Indian in the Cupboard and Ant-Man are all ones that have used different visual effects techniques to go small. These techniques have ranged from forced perspective, over-sized sets, shooting on blue or greenscreen and of course digital means.
Visual effects supervisor Eric Brevig happens to have worked on a coupe of these types of films, including one of my favourites, The Indian in the Cupboard, which featured visual effects from Industrial Light & Magic.
Here, Brevig shares his memories of that film and the methodology behind miniaturization.
b&a: What had been your experience with any miniaturisation effects prior to The Indian in the Cupboard?
Eric Brevig: I had done certain short sequences in other projects. I did a 3D, double 70mm Disney EPCOT film for the theme park around 1980. It was like a dream sequence for a pavilion that they built there about imagination. And part of the dream sequence had the little boy, who was the main character, imagining that he was looking at a miniature circus, maybe three feet across, filled with tiny clowns a few inches tall and so forth. Then later on he shrunk down to fit into somebody’s hand.
And so that was the first time I had to really wrap my head around how you shoot mixed scale characters like that so that the perspective is correct and so forth. And since that was a 70mm 3D, meaning stereo 3D, project, there was much less tolerance for cheating things like scale and perspective.
I also did work on the Honey, I Shrunk the Audience for another Disney theme park several years later and just continued the same sort of things. I was on Hook at ILM as well with Tinkerbell. It was very familiar territory for me by the time The Indian in the Cupboard came up.
b&a: What is the major thing you think you have to get right with any kind of scale or miniaturisation work?
Eric Brevig: You have to be able to have the tiny element look like it was photographed from the same camera as the large element. And that means all aspects of photography – depth of field, shadow size, obviously camera position and camera motion and lighting. In Hook, because most of the time Tinkerbell was a fairy character that was glowing, the lighting became a combination of casting her light onto the background.
I remember we had a scene that I’d actually proposed to Steven Spielberg because I loved it in the Peter Pan animation, where the little Tinkerbell character walks up Peter’s shirt. Robin Williams was wearing a shirt and we had the character, Tinkerbell, walk through an ink pad so she left tiny little footprints. And it was just a lot of fun to work with Robin and getting him to, in a very tight close up, track his eyes where I was going to composite in the Tinkerbell character, and I gave him a little guide to follow. And then on overscale piece of blue screen set, we shot Julia Roberts following the same path.
But one thing that’s kind of fun when you’re doing little characters like that is that you can speed up the action because little things can move quickly. So I was adjusting the timing so that, at the rate that an adult Julia Roberts, full size, could walk up a set that looked like somebody’s blue chest, laying down of course, that her character, composited in, would track exactly where his eyes had been looking.
b&a: With Tinkerbell in Hook, and in several other films like Honey, I Shrunk the Kids, one of the main methods was to build over-sized sets. And then there’s also shooting the actors against bluescreen and compositing them in, and there were some forced perspective shots. But was that kind of the idea, to mix it up a bit, so that audience isn’t really quite sure how you’ve done it?
Eric Brevig: Yeah, I think that’s the most fun. We did one or two forced perspective shots, which I love to do and I kind of, growing up really was enamoured with the work that the Disney studios had done on Darby O’Gill and the Little People, which was all essentially forced perspective. There’s maybe one or two composited shots in the entire movie, but most of it was very sophisticated forced perspective and mirror shots, where a front surface mirror is partially removed, revealing a background set that’s painted and lined up precisely to match the foreground.
When I was a student in college, one of my student films, because I had no technical equipment to do anything sophisticated, was basically a mixed scale student film, where I bought $1 mirror tiles at the local construction supplies store and carefully scraped off the silver from the back and lined it up with the foreground set and the background set. So that was all stuff that I loved to play with and experiment with as a kid. And then, because I think on Hook Steven really wanted to do that the old school way, my art director and I set it up for him, so we could make it look like Julia was in the doll house, and the doll house was in the foreground, and she was on an oversized set in the background.
But the reality is, it is so cumbersome to take the time to do that in front of camera, and so much faster and easier to use compositing and CG that we did it one time and they said, ‘That’s great, let’s not do that anymore, let’s just go back to the way you want to do it,’ which is using multiple photography elements.
b&a: Hook came out in 1991. By the time Indian and the Cupboard came along in 1995, had digital compositing moved on to a point that was even more beneficial for pulling off scale shots?
Eric Brevig: Well, it didn’t necessarily help with scale, because both the large scale and small scale characters were played by actors, so you’re obliged to photograph them both. If you have a small character in a fantasy world or in a CG world, life is much easier. But if you’ve got both characters, large and small scale on screen together in a photorealistic world, you’re obliged to come up with a way to photograph them both so that they both look like they’re in the same environment. And also, for the actors and performers, you have to come up with a way for them to interact and act together.
So a lot of the work on Indian in the Cupboard was to facilitate that kind of emotional relationship that was the core of the movie. It wasn’t a fantasy – well, it was a fantasy, but it wasn’t a spectacular visual effects extravaganza that was showing off, look what we can do. It was an intimate tale of two characters from different worlds and different scales who developed this emotional bond. So it was really important to allow the actor, his name was Litefoot, who played Little Bear, to be able to hear and react to, as an actor, this giant boy. And similarly I had to help the boy, who was played by Hal Scardino, find where to look and so forth and be able to act with the Indian actor so that there was this genuine sense of two people communicating.
b&a: I’m curious if going from optical compositing to digital compositing made any difference at all?
Eric Brevig: Well it didn’t really make a big change because essentially we were just replacing the clunky, mechanical, optical printer phase with the equally clunky, primitive digital compositing stage. But it gave me the opportunity to do some fun, nuanced enhancements. I remember there was a shot of, I think it was a cowboy, he’s supposed to be two inches tall and he’s walking across a bed with a comforter on it, and I had a big uneven surface that was blue and shot David Keith, who was playing the cowboy, walking across that.
And my director of photography is a fella named Chuck Shuman, who I worked with on a lot of movies, from Total Recall to The Abyss, and he’s one of the most precise and brilliant directors of photography in understanding how to match the lighting between a small set and an oversized set. And he would actually match the size of the lights, scaled up, when we shot the actors portraying little people, because that’s the way the light wraps around you, is the relationship between the size of the light source and the size of you. And so, when we would shoot the normal set, we would have normal sized lights, whatever size they were, a foot across, and he would rig, for bluescreen miniature people, I think the scale was like 24:1, 24 foot wide illuminated surface that would cast the matching shadows.
In any event, we would shoot these, but there really wasn’t a way to puppeteer how the footsteps would move the fabric because oversized fabric never looked convincing. One of the things that I learned early on was, if you can always shoot the non-miniature stuff on real sets with real cloth, like you would normal macro photograph, it adds a verisimilitude to the scene that you can’t get with oversized props and so forth, which are very difficult to pull off and not have them look a little bit like oversized props.
In any event, as our character walks across this blanket, we were able to digitally put in little divots and depress the cloth wherever his foot stepped, which just sort of locked him in, in a way that you could never had done without digital. Because we’re essentially just warping, or morphing a little bit, some of the background imagery as his foot is making contact. So there were really nice little enhancements like that, as well as just the ability to perfect the compositing edges and so forth, in a way that photo mechanical compositing did not allow us to do.
b&a: You mentioned a really cool thing there, which was matching lighting for when a character is shot big and when they’re shot small. What about camera movement, did you use motion control to match up small and large shot plates?
Eric Brevig: I would decide based upon the needs of the shot, which camera – because we had to photograph foregrounds and backgrounds with cameras because they were both real environments – which camera would lead the shot. Let’s say it’s the little boy and he picks up this tiny Indian and he moves across the screen with it in his hand. I would photograph that with a traditional camera, tracking the boy. And he’d have just a little tiny object, I think I used something that looked like a bent paperclip, so that he had something in his hand that was showing him where to put his eye line and kept him honest about how he was holding it, but was easy to paint out.
And then after we had shot that, we would analyse the footage within the duration of the shot that was intended to be used in the movie and we’d say, ‘Okay, here at the beginning we’re one foot away from his hand and six inches above that. Okay, well that’s equal to 24 foot back and 12 feet above.’ And so we would design a camera move, using a very big crane arm, so that we would, as the boy moves through the shot, the camera’s now six inches from the character and one inch above his head, well, that equals 12 feet back and six inches would be six feet above his head.
So, we would basically plot out in the real world what we were doing in terms of matching that camera. And because you have a lot of space for leeway when you’re moving a camera 50 feet through a sound stage, it doesn’t matter if you’re a little bit to the right or the left of where you’re supposed to be, because then by tracking the two and using digital compositing to lock the two together, you’re able to make the perspective of one non-motion control shoot fit the other one by sort of locking them together afterwards.
If instead the shot is driven by what the little characters are doing, well, there was one very nice shot where the camera’s creeping across the little boy’s bedroom, and we can hear the Indian is singing some sort of traditional song. And the camera peers over this toy box that’s in the foreground, and we see that the Indian’s sitting on top of this little half-built structure that’s going to be his home. So what we did is, we figured out the total distance needed at the scale of our adult actor, and it was like a 100 foot camera move, and then we’d come down and we’d peer over where the box would be and then we boomed down, basically into a close-up of him, and we shot that first.
And then by tracking it and using a motion control system to shoot the same move on a bedroom set, we were able to lock them together precisely in photography and really get that sense of no hindrance to the camera wherever it went, because we were shooting on a genuine bedroom sized set, rather than a little bluescreen of the Indian. All the depth of field and focus and all that stuff was exactly as it should be, so it felt like you’re crawling, you know, the camera sort of creeping through this room and peering over a little toy box and there, in shallow depth of field, on this half built house, we’d find the Indian character.
Once again, my director of photography, being aware of what we were doing, would take incredibly precise notes on, for example the bedroom set. Including colour temperature from each of the lights and positioning, and we’d really create that on the giant scale of the screen stage and the two fit together really, really precisely.
