If you wrote it set in the present day, they'd be a bunch of 50-somethings pining for the 90s, bucket hats, blasting Pablo Honey and Modern Life Is Rubbish from the Sharp "Full Auto Reverse" in the Astra, and bemoaning how you can't get decent E and no-one gets in fights any more. They probably own very expensive guitars, too, that they can't really play. The Kia e-Niro will run out of battery at the most inconvenient time leaving our trio stranded on their way to retrieve the stolen diamond to pay off the local councillor Ritchley, who is really fronting for a shadowy property developer who he is very much in love with but has no chance with.
They all dream of one day leaving Swindon.
Athos, Porthos and Aramis are Simon Pegg, Nick Frost, and Dylan Moran, Ritchley is Bill Nighy, and Milady is Tamsin Greig.
Quite a lot of people absolutely hate it, but somehow still have a pirate copy squirrelled away.
