"I am very excited and I am really very proud. Right now the movie is on editing table, we are keeping our fingers crossed now. It is indeed a very emotional story. It is a story about a father and his daughters," said Rao about "Dangal" at the screening of "Kapoor & Sons" where Aamir was also present. Kiran, Aamir and Disney production house's Siddharth Roy Kapur, have been credited as the producers of the film.
