(Watch: 'The Bank Job' - if you like allegedly D-noticed, fact-based royal sex scandals - past and present )

The British royal in question? A raunchy, randy female this time - none other than the very liberated, lost and louche Princess Margaret.

It is/was believed or alleged that one of the bank's safe deposit boxes contained many hard-core pornographic photos(bondage, chains, leather, masks etc) of high-profile establishment figures caught in the act in exotic-erotic locations..and very comproming positions.

Annie Machon(ex-MI5 turned truth-teller) does believe (and says so on the DVD's Special Features) that a D-notice gag-order must have been issued to the press. Why? Not least because despite the fact that the 1971 Lloyds Bank, Baker Street London bank-raid was by far the most daring and sensational to date and was initially given around-the-clock headlining newspaper, TV and radio coverage - all media reporting abruptly ended after just three days.

And also: despite the fact that the hushed-up 1971 bank-raid easily eclipsed the 1963 Great Train Robbery - that relatively clumsy half-botched train heist and in particular the hunt for Ronnie Biggs were by contrast allocated unlimited media coverage and police resources for decades.
(Contrast also with the non-pursuit of housemaid-murdering aristo Lord Lucan)

If you need more reasons to check out this highly-rated but now barely-known, rarely-mentioned film:
- David Suchet co-stars as a sleazy cockney villain
- the script/screenplay was largely written by Dick Clement and Ian La Frenais.
