'Kapoor and Sons' special to all of us: Karan Johar

It captures the on-and-off bond between Sidharth and Fawad who play brothers, Rajat and Ratna their parents and the overall ups and downs in the Kapoor family, while Alia gets involved with the family through her bond with the brothers at various points of the story.An interesting part of the trailer, though, is the 'old' Mr. Kapoor played by Rishi Kapoor.
