Shahid has already made a mark for himself in Bollywood with hits like "Jab We Met", "Kaminey" and "Haider", and Sanah entered showbiz last year with "Shaandaar".
Even though "Shaandaar" turned out to be a dud, Sanah's performance was appreciated.
"I think she (Sanah Kapoor) is a very fine actor. I'm very proud of her. But I don't want to talk about it myself because it seems like I am trying to talk about my daughter. So about my elder son (Shahid) as well as younger son (Ishaan), I have always said one thing that let time prove it to the audiences and what are the abilities they have as actors and as people," Pankaj told IANS.
Pankaj, who has explored various mediums for entertainment -- be it films, theatre or television, also feels Sanah has miles to go, and work to do to find a foothold in Bollywood.
He added: "I will say that she (Sanah) is a very fine actor, but it is just that the more she works, the more people will understand her ability."
Pankaj shared his views with IANS after attending an event organised by detergent Ariel India on the topic 'Why is laundry only a mother's job?' in Mumbai earlier this month.
