'The Accountant' is a great example of the finest of British black humour. It features the busy Alfred Molina in (what I think is) his best role... a mild mannered Jewish family man who gets sucked into the criminal Mafia underworld.
Lional Ellerman is an honest and hard working accountant. He's being taken advantage of by both his clients and his employees... but he's no fool and allows these things to happen to him.
He eventually gets inadvertently drawn into the Mafia lifestyle and is even a little star-struck by it as he starts organizing their accounts. While all this is going on, he's busy trying to organize his home life which includes his son's Bar Mitzvah.
It's a terrific story with a lot of heart combined with dark comedy, despite the rather sinister double life that the accountant is drawn into. Although the end scene is a mite disturbing, it is inevitably appropriate.
The scenes of the actual Bar Mitzvah are hilarious, but you always sense that there's something disturbing going on beneath the surface.
Frustratingly the title image for this TV movie is incorrect and it isnt even mentioned in Molina's IMDb profile.
If you like 'The Accountant', check out another clever dark British comedy 'Sleepers' from 1991.
