• “It was a conscious effort to construct as many sets as possible to make it look realistic, and then there was considerable help from the visual effects department (supervised by RC Kamalakannan) to provide extensions where necessary,” says Rajeevan. The ashram portion, for instance, was originally to be shot in the vicinity of Chalakudy falls in Kerala, but with Amitabh Bachchan’s dates being a constraint, the team had to shoot in Ramoji Film City and rely on VFX extensions. The visual reference for the ashram came from a set Rajeevan had designed for the AR Murugadoss and Suriya Tamil film 7aum Arivu ( Seventh Sense in Telugu).
