Animatronics
Animatronics is the process of building robotic models of humans or animals, or in this case beasts. They are programmed to perform intricate, lifelike movements in time with a pre-recorded soundtrack. Our animatronic beasts were made and operated by Crawley Creatures and Associates and below they describe the process of working on Walking with Beasts.
Dinosaurs versus beasts After working on Walking with Dinosaurs we thought Walking with Beasts would be a little easier, but it wasn't. The
creatures became bigger and bigger, and in contrast to the dinosaurs, hairier.
The process became more complex: as well as covering such large beasts with
fur, we had to do more animatronic work to produce a greater range of facial
expressions than the dinosaurs, as the mammals have to be more believable to
our critical eyes.
Travelling with the animatronics Finally came the difficulty of getting the
animatronics ready to be transported to locations in the far-flung reaches of
the world, trying to avoid a rainy season in one place or a winter in another.

The mammoth's head on location
|
We headed for the snows of the Yukon in Canada with a full-sized mammoth, only
to chase the snow across the territory as it melted. All of these things made the
animatronic build schedule difficult to stick to.
There was so much work that our core team of
seven grew to eighteen, with additional support from several specialist
out-workers. The majority of the team had an art college background - the
experience of life drawing and figurative sculpting provided a good
knowledge of anatomy.
Creating the models First, we used the
reference material provided by the BBC research team to sculpt the creatures in
water-based clay or Plasterlene. The sculptures were then moulded in silicone and/or glass re-enforced plastic (GRP), to provide negative moulds. From these moulds we produced a foam latex or silicone skin, an under-skull and a body-form.
The under-skull and body-form went to the animatronics "mechy" department, where radio-controlled mechanisms to move eyeballs, eyebrows, noses, ears whiskers,
arms and legs were built from scratch. All these movements are combined when
the model is operated to create snarls, snorts and blinks, and other facial
expressions.

Moving the models around Larger engineering work went into producing Steady Arm rigs, (similar to a Steady Cam rig worn by cameramen) that support the smaller heads during puppeteering.

The mechys also
produced the Sand Dolly, a
counter-balanced arm with universal movement. The Sand Dolly could be quickly assembled and positioned onto a
light-weight framework with Quad Bike all-terrain wheels, and was used for
operating larger heads such as those belonging to the
mammoth, Woolly rhino and entelodont.
Making the hides and pelts Meanwhile another team transformed the foam
and silicone skins into hides and pelts with flocked hair and fake fur. This had to be dyed to the correct colours, pattern cut and applied to the
skins by a special process to keep the skins flexible.

Putting hairs in for fur, one at a time
|
Often the technicians
had to apply the hairs one at a time, which was extremely time consuming and required a
lot of patience. The full-sized mammoth took several months to make with
several thousand pounds (Sterling) worth of Yak hair applied to the skin.
However, some of the beasts weren't hairy and needed only a hide, which required a
skilled paint job and a few whiskers, with some guard hairs punched in for good
measure.
When the skin and mechanisms were completed
the two elements were brought together with the skins being adhered to the
mechanised skull and body. Once final touches and mechanical checks had been
done, the completed animatronic beasts were shipped to location for filming.
Over 40 animatronic elements Over the one-and-a-half year duration of the
project, the team made and operated over 40 different animatronic elements.
There was a wide range of beasts, most of which were animatronic heads. For
example the two Smilodons, the sabre-toothed
cats, who fight it out in programme five, and the giant hopping, shrew-like
creature Leptictidium, which features
in programme one, were all made for filming in close-up.
Waterproofed electronics were needed to help
achieve the skilful underwater puppeteering of the early type of elephant Moeritherium. This enabled the film crew
to achieve the close-up shots of the head interacting with the surface of the
water and feeding on the seabed around the Florida Keys, USA.
Several full-sized bodies of creatures were
also made for shots involving interaction. For example, bodies being dragged
along or falling to the ground and moving the dust or water, or being eaten by
other creatures, and having blood and guts dripping from them. This can be seen
in programme six when a full-sized Cro Magnon tribe and the Neanderthals butcher a mammoth
carcass for food.
Neanderthals The actors playing the Neanderthals wore prosthetic make-up appliances designed by our
make-up team. Prosthetics were used on their faces, also wigs, bad teeth
(dentures) and beards for the men were added to complete the look. A
prosthetic make-up appliance was also used on an actor for an extreme close-up
shot of the male Australopithecus. The
actor also wore full-sclera contact lenses that cover the complete eye.
Most of the animatronics creatures were filmed in real landscapes on location, and our work didn't stop with the
completion of the build and the packing of the crates. All of the creatures
were puppeteered by two of our creature operators, often in difficult
conditions. An array of beasts travelled from Florida to Mexico, Java to
Arizona, Brazil to South Africa and to the frozen Yukon Territory in Canada,
where they made to walk the Earth again.
