"In order to get the backlight effect of the sun in Tyrell's office the whole
upper part of the frame was a series of big studio lights. After we did the
front projection of the actors moving in front of the window, the whole upper
part of the frame was removed and replaced with a matte painting. The sun had
to be opticalled in and rotoscoped and anyone who moved in front of the sun
had to be rotoscoped out."
-Doug Trumbull

This special effect shot shows the interior of Tyrell's office, where Rachael
first meets Deckard. The sky, sun, and crossing birds were added in during
post-production.

Deckard administers the sensitive Voight-Kampff test to Rachael and is
suprised and disturbed by the results.

Top Drawing: Ridley Scott's sketch for Tyrell's office emphasizes the vast
spaces in the room. Lower Drawing: Sherman Labby's storyboard sets the scene
as Deckard enters Tyrell's office and the mechanical owl sweeps across the
room.
