Plot holes trip up the Iranian director’s drama of a slippery man’s desperate efforts to trick his way out of debtors’ prison

Asghar Farhadi has made a tangled film about the tangled web we weave when first we practise to deceive, in that calmly observant, realist yet information-withholding style with which this director made his name. In way, A Hero is a slice-of-life story, in which the “i”s and the “t”s are not necessarily dotted and crossed like a regular screenplay; it has the unsatisfactory, unclear messiness that real life has. There is plenty of interest here - and yet I have to admit to slight reservations about the melodramatic contrivances, which stretch credulity a little.

A Hero is a film that works because of a clever and subtle performance from Amir Jadidi as Rahim, a divorced father who has just been released from jail on a two-day parole, having been imprisoned for debt. He is a man with a bright yet strange, desperate smile, like one of the poor relations in Dickens. He is looking forward to being reunited with his girlfriend, his supportive sister and his beloved son – a gentle, sensitive boy with a speech impediment. Rahim is a man who believes that some sort of charming niceness might still get him get out of a jam. But he has a very specific plan for cancelling his prison sentence. His girlfriend has found a handbag in the street containing what appear to be gold coins: if they could sell them to a gold dealer, might that not raise enough for a deposit to persuade his creditor to forgive the debt?
