"In spite of the terriffic pre-production drawings, when the spinner was
initially built and photographed, it looked like a flying brick. It took an
enormous amount of energy to make it appear aerodynamic and
interesting--continually adding flashing lights and other effects."
-Doug Trumbull

Exact blueprints of the police spinner were drawn by art director David
Snyder before attempting to build the flying vehicle.

One of Syd Mea's early drawings for the police spinner.

Incredibly detailed models of Deckard and Gaff are placed carefully in
the miniature police spinner for special effects and distance shots.

These Chinese characters read 'police.'

With Gaff and Deckard aboard, the police spinner takes off and heads for
Deckard's momentous meeting with his old boss Captain Bryant.

"There were four sizes of the spinner. One was four-feet long, another one a
foot long, one a half-foot long and another one four-inches long. Depending
on the shot, we'd use one of those sizes. Many times when you see many
spinners, it's just the same spinner used over and over again. There is an
Alfa Romeo spinner and a Lobster spinner, both a foot long. We gave that
foot-long spinner different appearances by painting it different colors and
lighting it a bit differently."
