How It's Used

“For the swimming scene, Flockhart was suspended in front of a green screen, doing the breast stroke.  That footage was digitally added to a shot [Mike] Listo [Ally McBeal’s special effects guy] took of the office full of smoke—on television, it looks just like water.”

“Director Robert Rodriguez, who had Mr. Miller on the set as co-director, shot the actors against green-screen backgrounds, adding the jutting buildings, shadowy interiors and other backdrops later through computer-generated imagery. The movie is presented largely in stark black and white, with a few splashes of color to highlight such images as splatters of blood, a woman's blond hair or a red dress.”
