I am not a box-office king, says Aamir Khan

"'Taare Zameen Par', '3 Idiots', 'Rang De Basanti' or 'Sarfarosh', when I did those films, I never thought they would do such a good business. If you take 'Dangal' as an example, I played a role of an aged and heavy wrestler. There are no romantic songs or any typical formula to become a blockbuster. Therefore, we never predicted that the film would be such a big hit," he added.
