you'd 'borrow' 97% of your participation from the scheme provider, write a cheque for the 3%, then it would just so happen that 40% of your total investment (including the borrowed bit, which was interest only) would equal your income tax bill. To pay the interest on the 'loan' bit you just assigned your partnership income from the film to the lender.
Then, before the 15 year (iirc) tax relived period was up you'd pay a firm a relatively small sum to buy your partnership investment from you, at which point your deferred tax bill essentially vanished (it would be based on the huge sum funded by the loan).
HMRC then slapped huge tax bills on people based on total participation amount rather than the amount of the cheque written when they decided the schemes were not intended to finance films after all.
I TOLD YOU IT WAS BORING.
