Already a huge success in its native India, Ritesh Batra's Mumbai-set romance arranges a tender marriage of Brief Encounter with Ernst Lubitsch's The Shop Around the Corner. Bollywood star Irrfan Khan plays Saajan, an ageing office drone who finds the wrong lunchbox delivered to his desk and stumbles into a chaste relationship with Nimrat Kaur's unhappy housewife. Before long, this pair will learn the value of crossed wires and missed connections and how (in the words of one colleague) "the wrong train can get you to the right station". Who cares if the conceit feels a shade schematic? The Lunchbox is perfectly handled and beautifully acted; a quiet storm of banked emotions. I loved the bittersweet scenes of Saajan clinging to the handrails of the crowded commuter carriage or smoking on the terrace of his home at night, like the loneliest figure this side of an Edward Hopper painting.
