"Now that Ritu da (director Rituparno Ghosh) is no more, we keep telling each other that we must work together. We are looking for a script which suits us both. I hope we will find it soon," Balan told reporters here.
In town to promote her film 'Bobby Jasoos', Balan said she and Prosenjit always keep in touch with each other.
"I make it a point to meet him whenever I am in Kolkata and he gives me DVDs of his films. He had encouraged me a lot when I was new in the industry," she said.
The actress has always maintained that Kolkata is her second home and many of her films like 'Parineeta' and 'Kahaani' have been shot in the city.
In her next film which releases July 4, she plays a detective.
When asked which case would she like to solve in Kolkata as a detective, she hinted at the multi crore Saradha chit fund scam.
"There are many scams here. I want to bust that," Balan said.
