"Audience will get to see all those elements in the film which they don't get to see in other films. If you want to see good actors and performances, then you should watch this film," the 38-year-old said here Thursday in an interview.
"In other films, audience are used to seeing costume drama. In this film, you will get to see acting. All the actors are very good," he added.
He was applauded for his role of Faisal Khan in 'Gangs of Wasseypur 2', but says his character in 'Chittagong' is completely opposite.
"It's a very soft and romantic character. Romance is done within limits in this film unlike 'Gangs of Wasseypur', in which there were no boundaries for romance. There was no need to seek permission before touching. There is nothing like this in 'Chittagong'," Nawazuddin said.
He has been in Bollywood since 1999, when he played small roles in films like 'Shool', 'Sarfarosh' and 'Munnabhai MBBS'.
However, he gained recognition as a small-town journalist Rakesh in 'Peepli Live' in 2010. He will next be seen in Aamir-Khan starrer 'Talaash'.
