In Bollywood, while one keeps on hearing about catfights between two heroines, but this one is an unheard of ever before. This is possibly the only sister jodi in Bollywood, Riya Sen and Raima Sen, both of whom 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. If our sources are to be believed, then, 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. What's interesting about the entire episode is that both the actresses are playing roles very contrary to their public image.

Our well placed sources revealed that while Riya Sen will be seen in a complete de-glam avatar, Raima will be playing a sophisticated woman.

Speaking about her experience of working with Riya, Raima said, "It was nice to watch her do 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 Rituda'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 naïve village belle."

Riya stated, "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."

Talk of being life-time members of the mutual admiration society!
