We've often heard of cat fights between the two leading ladies of a film, but what happens when 2 sisters are working together in the same film?

We are talking of the bong sisters Riya and Raima Sen who will be seen sharing screen space together for the first time in Rituparno Ghosh's ‘Noukadubi'.

Apparently Rituparno had approached Riya and Raima for the film at the same time and both of them even received the script together. They were offered two very diverse roles and both of them had no qualms playing the characters.

However, according to our sources, Riya initially thought Raima's character had a lot more prominence and had much more scope and dimension to it as compared to hers.

But being a thorough professional and a doting sister, Riya chose to go ahead with the role she was offered, as it was extremely challenging.

Interestingly, both the actresses are playing roles very contrary to their public image.

While Riya Sen is considered to be a sexy siren who can give half the population with the Y chromosome sleepless nights, in this movie she will be seen in a complete de-glam avatar!

And on the other hand, Raima, who is known for her intelligent and matured roles, will be playing a sophisticated woman.

And what did Raima have to say about her experience working with Riya? "It was nice having to watch her doing such a complex character. She was so easy and comfortable on the sets and with the director.

Everyone pampered her silly! This is the first time I've played such a mature character in Ritu Da's film. I play the character of a learned and sophisticated woman who holds her own in any situation. It's quite a contrast from Riya's character, who plays a naive village belle."

On being asked about the experience of shooting in Kolkata, Riya giggles, "Raima pampered me silly on the sets. Right from organizing the best make up vans and acquainting me with the staff in Kolkata, she was always a phone call away and kept everything prepared for me! Sometimes I felt I was treated like a baby, it felt like my first film!"

And while both sisters are aware of the comparisons that will be drawn, they are more thrilled at the prospect of featuring in the same film, under the able hands of acclaimed director Rituparno Ghosh. We sure can't wait to see the sister duo in action!
