"For Chew's laboratory we found a large meat packing plant in Downey. Before
we began filming, they had to start to lower the temperature because if you
just turn the thermostat down to zero or six degrees, the concrete walls
crack, all sorts of funny things things happen. You have to turn down
gradually. Over the period of about two weeks the owner turned it down to
about four degrees below zero. We put up the set about four days before. For
the next couple of days, we sent a crew down there with spray cans and they
proceded to ice up the walls. We not only iced up the walls, but we ended up
having icicles two feet long, real icicles, hanging from the ceiling and real
ice. It was cold!"

contentedly in his arctic laboratory.

Batty and Leon question the terrified Chew about their genetic design and
their chances for survival. Chew informs them that Sebastian can lead them
to their maker.
