At the inauguration of a short film festival, named 'Shuruaat Ka Interval', here Wednesday, Ranbir was asked about the one person on whom he'd like to make a short film.
To that, the handsome heartthrob of Bollywood said: "I would like to make a short film on my grandfather. His life was very entertaining and interesting. I think that would make for a good short film."
The late Raj Kapoor, one of the country's most formidable actors and filmmakers of his time, remains alive in people's hearts with his evergreen films like "Shree 420", "Mera Naam Joker", "Anari" and "Barsaat".
