Amitabh Bachchan calls Irrfan Khan's death 'tragic', posts video tribute for Rishi Kapoor

Megastar Amitabh Bachchan believes the demise of his "Piku" co-star Irrfan Khan is "tragic" because his potential as an actor was left "unrealised".

The 77-year-old actor on Saturday posted a tribute to both Irrfan and veteran actor Rishi Kapoor who died within a day of each other after their respective battles with cancer.

In the post on Instagram, Bachchan touched upon "the death of an elder celebrity vs death of a younger one" topic.

"The death of an elder celebrity vs death of a younger... the grief of the latter more intense than that of the former... Why...? The younger more tragic?
