We all know how talented filmmaker Vishal Bhardwaj is. He has given some of the greatest movies like 'Omkara', 'Kaminey', 'Maqbool', and 'Haider' among others. But some of his films failed to do wonders and they were duds at the box office. Shahid Kapoor, Kangana Ranaut and Saif Ali Khan starrer 'Rangoon' is one such movie which tanked despite having such a huge star cast. In an interview, Vishal opened up on his regrets about the 2017 film.
