Dan Curry:
"In the episode Voyager encounters large scale viruses. And when
we were coming up with a design for those inspired by the design
of diatoms which are a microscopic organism on Earth that is
used as part of a swimming pool filter system, dyed a tenacious
earth to make them look nasty and threatening. Instead of having
the normal rigid exoskeleton that a real diatom has, we changed
the prongs on its tetrahedronal shape into grasping tentacles.
And then for the stinger a full-scale stinger would be like this
(displays model) And there were a couple of scenes where they
had to push through the turbolift door and squirt their poison
on people."
Dan Curry:
"And there was one
scene where Kate Mulgrew as Captain Janeway was having a close
encounter with a giant virus, and as she was laying on the floor
it kept trying to sting her in the face. So just out of frame I
was standing with this, and making sure I didn't hit her in the
face but poking it so Kate could avoid doing it, and when it was
over we had a lot of laughs because it certainly was bizarre and
very unpleasant-looking."
The
computer-generated image of the macrovirus which attacks Janeway
was added in post-production. To make it easier to put in the
footage of the CG creature later, Kate Mulgrew filmed her
dodging movements against a blue screen. When acting Janeway as
she seizes hold of one of the creature's tentacles, Kate Mulgrew
mimed the movements. The CG creature was added to the footage
later.
