This creature is, according to animation director Robyn Luckham, a human that has been experimented on. No indication is given as to their identity.
So, the big question I had [for Denis] was is this a human with limbs attached to
it, like it's a spider? Or is it a spider which has a human form? And
it's when you start thinking about it that it's disgusting.
Really what it is is it's an experiment, kind of like, it's a human
but it's not actually got legs or arms.
Denis found this reference of this incredible ballerina who does a
ballet performance like a spider.... Denis contacted her and we got
her in a mo-cap suit and she actually performed on the day and became
the backbone reference of what we're doing.
The thing for this one is that it's all about posing. We had to get
these poses to read how this thing is working, to feel comfortable but
awkward, because again, going into this biology, this is not lived as
this creature her entire life, bred for that purpose, it's just been
put together, so it's hard to walk.
