Kattappanayile Rithwik Roshan is still in theaters but it has already been marked as one of the blockbusters of 2016 at Kerala Box Office. As per our box office source, the movie has collected Rs. 17.80 crores from Kerala in just 40 days. This is more than a remarkable figure for the movie which doesn't have a star-studded cast to back it. This also means that Nadirshah has got a place in the elite club of directors who have given back-to-back blockbusters.
