The Accountant (Affleck) is someone who makes an off-the-grid living doing auditing work for criminals; and he’s twice as dangerous as they are, because he has to be. A mathematical genius who grew up with autism and a military father, he’s learned to defend himself against anyone. He has something better than CPA accreditation – he has autistic licence. Sorry.

In our story three things happen to The Accountant for the very first time: he takes on a job that’s not actually illegal; he starts to attract the attention of the FBI; and he begins to fall for a woman (Kendrick), also an accountant, and she with him. Two of these three things are not quite what they appear.

The starting point for the film seems to have been: ‘Let’s have an action star with the least exciting possible profession’; and that, so popular folklore assures us, is accounting. And yes, it’s fun watching an impassive introvert dressed like a Mormon as he punches and shoots his way through a thicket of mercenary assassins – but the plotting is smart, and the character is intriguingly developed, so that the film has more to offer us than just this guilty pleasure.
