"A late bloomer for sure," laughs Aditya. "But then who decides what's the right age for anything in life?"
After Ranbir who's half his age Aditya is happy to be the latest Kapoor to make his appearance on the shimmering screen.
"I'm very happy for Ranbir. He has done all of us proud. His father, my nephew Rishi Kapoor has acted in two of the films I've directed Sambar Salsa and Don't Stop Dreaming. Both international projects in English."
In fact Don't Stop Dreaming features the bhangra-rap singer Taz from Stereo Nation.
Says Aditya, "Not too many people know of Taz's acting debut in my film....Just like they'll be surprised when they see Shammi Kapoor's son acting at the age of 51."
Shammi Kapoor has in fact given sonny-boy his blessings. "I'm nowhere near my father. And I don't aspire to be. I want to slot myself in the kind of roles that Sanjeev Kumar used to do ...Or for that matter Mr Amitabh Bachchan.
Man, what a phenomenon! He has paved the way for all the young-at-heart 50-plus actors who want to play the lead. In a film like Cheeni Kum Mr Bachchan has taken screen romance to another level. If it wasn't for him I wouldn't dream of turning actor at my age."
Aditya already has several offers. In fact he has just completed a Hindi film where he plays an older man in love with a 24-year girl. But he's not at liberty to talk about the project.
"Producers have already come to know that the oldest Kapoor debutant is available," laughs Aditya. "But that doesn't mean I've put my directrial career on the backburner. My next directorial venture Balti Devi Queen Of Southall with Rakhi Sawant is very much on."
The project got delayed when the film's leading man Vinod Khanna decided to do television, and that too in a flop serial. That's when the projects financiers deserted Aditya Kapoor.
"And that's when I decided to let the actor within me take over," reveals Aditya. "Direction is far more time-consuming. Acting which is in my genes is far quicker and financially rewarding process. I've always gone where my heart takes me. I left India.Directed film abroad..Came back after 25 years. Now I want to act. It's never too late."
