Moving The Puppets: Wrestling A Shark
Creating a stop-motion
sequence is a slow, deliberate process of making tiny changes
in the model, shooting one frame of film, making another change,
shooting a frame, and so on. Most models are small and fairly
easy to manipulate by hand, but the Jaguar Shark was particularly
difficult to handle. Kohn had to turn to powerful motors to
animate the shark puppet:
"We actually
had the biggest puppet, some people said the biggest stop-motion
puppet ever made, which was about eight feet long and about
130 lbs. And that thing, I barely even animated it. I animated
the jaws and the gills and the fins and the tail and all that
stuff. But to actually make it move, make the whole puppet
move, that was done on these motion control rigs. Big, powerful
motors that were on tracks. So the puppet had three or four
controls...We'd say, the puppet goes from here to here in
200 frames. And we'd take the midpoint and move it back and
forth on 24 frame increments, and then we'd offset it to the
three behind it, and then we'd polish those, to make it look
like the whole body was undulating."

The mighty Jaguar Shark
"A 130 pound
thing with joints as big as my hip joint would have been really
hard for me to move it... When I had to make his head move,
I had to put my whole body under the puppet and lift up, just
to bend the joint with my legs, 'cause it was such a huge
thing. But for the undulation of the body, it would have taken
forever to animate it 200 frames with the size of the thing.
So we let the go-motion rig do it."
