I used to work near to the Heathrow Trading Estate where the Brinks Mat robbery took place, and although I was there a few years before it all happened, I'd say that the clothing and general appearance was just about right. I worked with someone who had the very line in Emun Eliott's clothing, right down to the early '80s moustache.
The Gold take the era and plays with smoke-filled rooms and cars, swirly sticky carpet pubs and those kind of offices which set up thin partitions and groups of desks, well before computer terminals became the thing.
The robbers accidentally stole £26 million of Gold Bars, weighing 3.5 tons and proceeded to smelt it down, repackage it and then re-insert it into the market, using offshore accounts, then spending the money on apartments to break up the trail.
Come to think about it, it reminds me of The London Laundromat, which is purportedly still running.
Excellent casting and a lightheartedness which suggests everyone enjoyed their part in the proceedings. Checkout Hugh Bonneville doing his best to look like a heavily promoted Dixon of Dock Green. We had our share or writerly interludes within the piece too, where a particular soap box was stood upon by means of a discussion between the characters. I found this interesting at the beginning, but it slightly dipped later in the series.
But how that gold shone, at least before the mangled comedy melted bars were introduced. And the device of a diagram which comprised 'move A to B', explained dutifully by the seconded HMRC expert.
I still found it a fun piece of television and it looks as if they left it open for a second series to see what happened to the rest of the loot, or at least a spinoff.
