It could be a great movie-making satire, along the lines of Argo, or Mel Brooks' The Producers. The pitch: a team of amateur crooks concoct a bogus movie to squeeze millions in tax relief from the government. They claim it cost £20m to make; they get around £3m back. Sorted. Until the taxman asks to see the film. So the crooks hastily dupe some C-list actors into cobbling together a cheap gangster flick. The twist? Said flick turns out to be pretty good. It even wins an award.
