Doctor Who

The first Doctor was, in appearance, an elderly man. Viewers first met him when teachers Ian Chesterton and Barbara Wright followed one of their students, Susan Foreman, back to her 'home' which turned out to be a dark and gloomy junkyard.

The Doctor was her grandfather, and Ian and Barbara found themselves whisked away for a succession of adventures in his incredible space and time machine - the TARDIS.

How Doctor Who's TARDIS, (Time And Relative Dimensions In Space) travels through space is a mystery, although another Doctor, 'Emmett Brown', discovered the secret of time travel in the movie 'Back to the Future'. But his 'souped-up' DeLorean car is surely no match for a Police Box.
