You bring home cut-price detergents, tonic water, Betamax tapes, and none of it works. I’m drowning in your rubbish. What did he tell you? Did he say he’s this big businessman, ‘cos he’s not. He’s a failure. Born failure, that one. Rose needs a proper father, not one who’s flannelling about like some big kid. Jackie, I’m making a living, it keeps us fed, don’t it?


David Tennant playing with the ice gun

Totally Doctor Who (Season 1, episode 5)

From the accompanying interview with Noel Clarke:

The special effects guys - they have a cold, ice-blowing machine that would have a tube coming out of it, leading all the way up to the back of the ice gun, which would be hidden away, so when David actually pushed the button, the metal pipe down the middle of the ice gun would actually shoot all this cold air from the proper contraption.  So when he was actually doing it, it was actually working.  If you did touch it after that it was freezing cold.
We have a lot of fun on-set.  On how many shows do you get to play with alien stuff and push buttons and have sort of ice-gun-y things?  I think whenever we get a chance or just five minutes when we actually get to sit down, if there’s props around to play with, we’ll play with them.
