Nambiar noted that Neil Nitin Mukesh's scenes were the most problematic to shoot as a result of the actor's involvement in his other film 3G being shot in Fiji and thus dates were difficult to accommodate Shilpi Shukla did great in the movie to. Akarsh Khurana, a theatre actor, who also helped write portions in the film, was also selected to play a major role and shot for scenes in Neil's portion. Monica Dogra was chosen to portray the female lead in this segment, being paired opposite Neil Nitin Mukesh. Anupama Kumar, who was previously seen in Ishqiya, was one of the few South actors to be recruited to act in the Hindi version; she would play a Pakistani woman of the 1970s which she termed as "very different and exciting". The scenes involving Neil's character would start in Canada and finish in Ooty and completed by the end of 2012. A five-day shooting was held at the City Hall of Belfast, Northern Ireland, UK in September 2012. The film was enticed to Northern Ireland on the back of a trip to India earlier this year by Enterprise Minister Arlene Foster. In a collaborative effort between Invest Northern Ireland and Northern Ireland Screen, Indian Production company Getaway Films has received £30,000 funding through the Northern Ireland Screen Fund supported by Invest NI and part funded by the European Regional Development Fund. The film was widely supported by the Northern Ireland Screen Initiative.
