Forget Doctor Strange or Sherlock Holmes, Benedict Cumberbatch has finally landed the most ridiculous role of his career after being cast as Vote Leave campaign director and Michael Gove advisor Dominic Cummins in a new Channel 4 film about the EU referendum.

The announcement has prompted speculation about who else will appear in this surely scintillating drama which, as the whole of the UK knows, has no clear ending.

It's believed Jeremy Corbyn will be making more of a cameo appearance in the production, as he did during the referendum itself, but there are plenty of other roles up for grabs. Until we find out for sure, here's who we suspect might be getting the call up for this sad tale of hubris, backstabbing and some very British faffing.

David Mitchell as David Cameron

Mitchell is already accustomed to playing a man as square as a packing crate after his years as Mark Corrigan in Peep Show. Since the Channel 4 series ended he's written several thinly-veiled anti-Tory pieces for The Guardian so he'll surely relish hamming up Cameron's role in leading the country into an infinite stale mate.

The comedian may be unwilling to part with his recently sprouted beard for the role, but it's not beyond the realms of imagination that DC has forgone shaving while holed up in his £25,000 memoir-writing shed.

Hugh Laurie as Nigel Farage

It was Laurie's various iterations of a shouty, deluded buffoon grasping for power on Blackadder that first put him in mind for the role of Nigel Farage. Laurie is a classic liberal luvvie who lives in leafy North London, owns a mansion in Hollywood and probably doesn't even smoke - so it's a casting appointment sure to upset 'Man Of The People' Nige.

Owen Wilson as Boris Johnson

Films based on real life are forever upgrading their average looking characters to Hollywood-levels of handsome, while retaining a token physical attribute. Like silly blonde hair, for example. Plus, Wilson has shown he has the range to tackle Bojo after years playing selfish idiots in bromantic comedies. All he has to do is lay off the gym for a bit.

Mark Rylance as Michael Gove

In order to get something close to the malfunctioning human suit that is Michael Gove, you better call in one of the best actors of all time.

Rylance's flawless Shakespearian credentials should prepare him nicely for a role in which he goes crazy chasing power, stabs his friend in the back and ultimately disappoints his wife.

Stephen Merchant as Alexander Nix

Well - he really, really looks like him doesn't he?

Julie Walters as Theresa May

The star of Dinner Ladies might seem like a soft choice for the Iron Lady 2.0, but let's not forget that in the halcyon, pre-referendum days Theresa May was a relatively anonymous Home Secretary whose naughtiest moment was running through a field of wheat. (Unless you count cutting police numbers or a hostile immigration policy which saw 'Go Home' vans sent around BAME areas.) Walters has also played many roles in which her character has had to deal with a series of feckless men getting in her way - useful, considering the current state of the cabinet.

Bill Nighy as Jean-Claude Juncker

If only to see Daily Mail readers implode at the sight of a British institution playing their favourite elitist bureaucrat.
