According to Shane Meadows (and his producer, Mark something-or-other), you get a few mates together (particularly if you’re mates with Paddy Considine), call in a few favours with the Arctic Monkeys, and trust to luck that you get enough usable footage. According to Roger Corman, it’s all about planning ahead.
“It’s time for a new dance”
“God is our guide! from field, from wave, From plough, from anvil, and from loom; We come, our country’s rights to save, And speak a tyrant faction’s doom: We raise the watch-word liberty; We will, we will, we will be free!”
