Inside TARDIS, with the police box doors in view (Dr. Who and the Daleks)
TARDIS was a space-time vessel invented by the Human scientist Dr. Who. It was larger inside than without and filled with electronics and masses of wiring. Its exterior resembled a police box. (Dr. Who and the Daleks, Daleks - Invasion Earth 2150 AD)
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, thus making it a mystery why it resembled a police box on the outside (though it's likely Dr. Who simply used an old police box as the shell for TARDIS).
