Although later, the transport authorities told us that it was not safe to shoot any action sequence on a moving tram, we shot the sequence on location as much as we could around December last year. For this, we needed to rethink on what could do with CG in the scene; there are large components of the Dublin sequence where the tram is actually made in CG. It was important to recreate the street outside the tram, because the tram cannot go over the same place as this would disturb the film and create jerks in the shots. This was a very challenging sequence wherein we have worked from January right till the release. It took over 7 months to accomplish this sequence; we worked on all the action scenes alongside.</span>
