Yes you heard it. One of our daleks developed a squeak. Didn't do it before and hasn't since, but at Pinewood it squeaked. It could have been David though who was chosen to operate it. He hasn't the same arthritic joints of Ashley but perhaps inherited them for the day. Not normally a problem but the sound guys picked it up!
Here's David being prepared for the scene - ie he's sitting minding his own business in a dalek base in Pinewood - as you do - and some oaf (Ashley) goes and puts a dalek lid on him before he's even asked for the oilcan. Typical
