The "Style" actress, 35, said she is rather getting the kind of roles she wanted to do in Bengai films these days.
"After working for 17 years in Bollywood, I am no longer interested in earning money only. I want to do roles to feel excited about. I want to enjoy what I do. And if you don't enjoy you will get bored," Riya told PTI.
Riya is playing Sheena Bora in upcoming Bengali film "Dark Chocolate"m which is loosely inspired by real events.
Her most outstanding role in Bengali films to date was in late Rituparno Ghosh's "Noukadubi" - the type of character she loves to portray.
Riya, the younger sister of Raima Sen, said she is portraying a gangster in "Senapati" being directed by Arnab Ringo Banerjee.
"I want to do different roles. In 'Jaatiswar' I got a special role and yet I was noticed. In the widely appreciated 'Family Album' to 'Kolkata Calling' by Moinak Bhowmik not a single role was identical and that gave me satisfaction," she said.
