This episode called for five times the animation and compositing
than our previous episode. All of the underwater footage including
the Mako shark, Erwin on his speeder sub and various other sea
creatures would have to be created and animated in the computers.
from removing the shorelines, other computer composites would
have to be created. Erwin's one and a half gainer off the side
of the boat was an impossible task for any stunt person, so
a CGI Erwin was animated instead. A 3D replica of the boat had
to be animated in sync with the real boat, as well, in order
to create Erwin's shadow on the bow as he launched upward.
the stunt footage of actor Cliff Barrineau was shot, images
of the Mako gnashing at him were composited into the scene as
he becomes the bait for the hungry shark. Cliff's boat ride
was real and performed on a January day, where the temperatures
dipped into the low forties.
