The answer is simple ... like some of the other non-genre films that I adore (say hello The Holiday and Airplane! - and of course The Stranger in Our Bed :)) it's a brilliant film, and very underrated and overlooked ... so I thought I'd try and share some love and get people seeking it out.
Released in 2013, and written and directed by Ritesh Batra, The Lunchbox contains a simple idea. In Mumbai, when the menfolk (and I assume womenfolk too) have all gone off to work in the city, their partners prepare their lunches at home. From what we see, these are usually some curries, vegetables, some chapati and so on. Similar lunches can also be ordered from companies who provide the service. Once they have been prepared, the lunchboxes are packed and then collected by a small army of people called dabbawalla ... these folk cycle and collect the boxes, then consolidate them all to go into crates on the trains, to be taken into the city, and then, using some arcane system of knowledge, get distributed to the offices and onto the desks of the workers, so they have a hot, freshly prepared dinner at lunchtime.
It's a superb idea, and the film does well in showing the process at work ... in a crowded Mumbai, people everywhere, somehow these boxes reach their intended recipients ... well ... all except one.
I love the film. It was recommended to me by a friend at work, and I managed to find a copy ... It manages to pull at all the right strings in presenting a very human story through the most unlikely of circumstances ... Ila's 'Auntie' is a brilliant creation. Never seen, but always there with advice and help and consolation. The scenes of Mumbai are brilliantly shot, and the offices and the people are as real a depiction of the culture and the people as I have ever seen.
The film is in Hindi, but has subtitles in English, but with such a good film this doesn't matter as the performances and the story pull you through. I'm not going to reveal how it ends or the twists it takes as it's worth seeking it out yourself!
But don't take my word for it ... according to the Wiki, the film won the 'Critics Week Viewers Choice Award' also known as the 'Grand Rail d'Or'. It was a box-office success and received unanimous critical acclaim. The Lunchbox was also nominated for 'Best Film Not in the English Language' at the 2015 British Academy Film Awards.
