Good Lord, the NOTES, you lazy incompetents!

I don't usually get too geeky with details like this, so I don't notice or mind minor anachronisms while watching, like a car model or reg. plate being a couple of years early, but the bloody banknotes, argh! I noticed them STRAIGHTAWAY, it was like a damn beacon! Especially the £20s, which were close to being TWO DECADES outside of the period! The newer design was only introduced barely more than a handful of years ago, it's not like it was a lifetime ago, so the changeover is still fairly fresh in my memory (and no doubt, in the memory of EVERY RAVER WATCHING, even the ones who were abusing their brains pretty hard in the 90s).
It took me right out of the story! You simply cannot afford to mess up like that when you know a HUGE chunk of your audience has lived through the period you're portraying!

I really can't believe that NOBODY on this weak flick spotted that - I wouldn't expect the younger actors to, maybe, but anyone over the age of 30 working on the film, COME ON!
After that, how difficult would it have been to get hold of the correct bills, and just photocopy them for the piles and use a few genuine bills for the close-ups, FFS!
