TARDIS (Dr. Who and the Daleks)

TARDIS, the space-time vessel invented by the Human scientist Dr. Who had within it a dark empty space larger inside than without filled with electronics and masses of wiring. Its exterior resembled a police phone box.

Behind the Scenes
The interior of TARDIS (not called "the TARDIS" in the films) did not use the familiar television set-up of a central console with walls on each side, but more a random assortment of technological apparatus. The dialogue did not indicate that Dr. Who's TARDIS could change shape, making it even more of a mystery that it resembled a police phone box on the outside.
