Considering that the banners are UTV Motion Pictures and Dharma Productions, the trailer you get is of a very offbeat interaction between a widowed employee played by Irrfan Khan and Nimrat Kaur who essays a lonely housewife. Letters are exchanged in the time of emails, an observation made by Nawazuddin Siddiqui, Irrfan's colleague in the film.
The tone is realistic, relatable and slow; in contrast to the rushing pace of the city (the train montages drive that point home). And the trailer does take the audience from the aroma of smoky spices in a middle class home to the musty yellowed interiors of an office. The lead protagonists' voiceovers dominate the trailer, backed only by mild, uplifting music and cutting between their daily routines.
Some fine sensibilities have gone into making the film. The Lunchbox has, in fact, won the Critics Week Viewers Choice Award at the 2013 Cannes Film Festival. Directed by Ritesh Batra, the trailer of the film is very promising. One only hopes it does not go unnoticed in the hype of the 100 crore films.
