No similarity between Sridevi in Sadma, Priyanka in Barfi

Basu`s directorial venture `Barfi` features Ranbir Kapoor as a deaf and mute person, while Priyanka plays a mentally challenged girl.

"People might feel so because the last film that featured the actress in a mentally challenged role was of `Sadma`. But the comparisons are only on the basis of the promo...once you see the film upon its release everything would be clear," director Anurag Basu said in a statement here.

The 1983 hit film `Sadma` featured Sridevi as the mentally challenged girl opposite Kamal Hassan.

Sridevi is all praise for the dusky beauty, Priyanka Chopra. "She is very versatile actress. Looking at her films like `Kaminey` and `Saath Khoon Maaf`...I miust say she is superb," Sridevi said.

Both Ranbir and Priyanka will be seen in a different avatar in `Barfi`. "Priyanka and Ranbir are doing non glamorous roles in the film and I wonder how people would react," Basu said.

The director revealed that they shot in real locations in Kolkata with hidden cameras.
