Katek - brilliant comment, I especially liked this:
"Even a single cameraman and sound guy just wouldn’t fit, so the whole interior has been built as a set and I think they’ve done a pretty good job trying to fulfil the set requirements. The production company couldn’t really rock up to Faslane and ask to hire out a nuclear sub by the day ( cue offstage shouts of ‘come in number 57, your time’s up!’)."
I half expected to see a Vickers (sorry VSEL) electrician, technician, plumber and or various others - hiding around the corner of those well spaced missile tubes. (Obviously keeping a 2m distance!!)
The story's entertaining though - reminds me of the incident a few years ago, when a security guard swam across the dock, hoping to remove one of the tiles from the vessel then being fitted out. He was caught and prosecuted.
