Not entirely serious

They probably weren't illegal as such, just based on advice from a friendly barrister which proved to be incorrect. Such barristers will tell you what you want to hear.
There are plenty of film investment schemes which are perfectly legal where the individual can legitimately offset/"invest" their tax bill. The problem is more with the unscrupulous film producers where the intention on their side is to make a loss or there is never an intention to actually make the film in the first place!
I hope HMRC looks to improve rather than remove the current film tax/investment options.
