While filming in the London Underground, the abandoned tunnels had accumulated so much dust and was so extensive that the crew had to wear masks while filming.
Once having a budget of £100,000, the crew and director Walter A. Stern filmed a video in the London Underground with Keith Flint in a straitjacket and other 'nonsensical & ridiculous' things. Then used £20,000 left over and filmed a little more, this time in black and white.
