"Sanjay himself has written the film and I feel it's for himself only. Of course, we all want Sanjay to get married and find the right partner for himself. Eventually, everyone wants a companion in their old age. So why not, to have someone with whom you can share everything," Bela told.
Bhansali, who is 49 and still single, realises that the story that he has written for his sister's directorial debut - "Shirin Farhad Ki Toh Nikal Padi" - is actually happening in his own house.
"Sanjay is saying, 'My god, this problem is with my family and my mother.' My mom keeps saying him (Sanjay) please have this, do this and Sanjay is like, yes mamma..Yes mamma.. It is there in each family and in my film also."
Bela, who has edited her brother's all films except "Saawariya" and "Guzaarish", has made "Shirin Farhad Ki Toh Nikal Padi" with Farah Khan and Boman Irani in the lead and says she loves experimenting and took it as a challenge.
"I am like this. I like to take challenges and experiment with my characters. It is not done for experimenting. I always had this thing in my mind that people can fall in love at any age. This is a subject which is a discussion in each house -- get married, get married, (umar beeth jayegi)," she said.
"Even my brother is not married. To get married is the perennial thing in every family and this film will give hope to 40-plus people who are not married. It can happen in any age. There is no expiry date for this," she added.
"Shirin Farhad Ki Toh Nikal Padi'" is slated for a Aug 24 release.
