Actually, for the pilot in particular, Kosh only has to move very stately
and slowly from point A to point B, so there wasn't much that needed to be
told. For a longer period, on the series, he would be played more as a
cypher...the less that can be revealed, the better. The only people directly
involved who had to know was the director (for certain attitudes) and the
costume designer (to incorporate certain elements and leave room in
appropriate sections).
