Has anyone seen the brit movie The Bank Job, based on the true events that took place around a 1971 robbery of Lloyds Bank in London.

I had never heard of any of this before seeing the movie, probably due to the fact that it was covered up by MI5 to protect the royal family, but it has fascinated me since seeing it.

Does anybody know how much of the film really happened? Is it an accurate account of the events or is it just loosly based on them?
