"Training is very important - be it a theater actor or a movie actor. Right kind of training brings out various shades of an actor and it is appreciated by the audiences," Nawazuddin told IANS.
The actor is on a roll as his two forthcoming films - "Miss Lovely" by Ashim Ahluwalia and Anurag Kashyap directed "Gangs of Wasseypur" were screened at 65th Cannes International Film Festival.
"Movies made now are very different and that is why viewers are liking them. Till now the audiences knew that there is a hero, a heroine and a villain and that there will be with some action sequence, romance and song dance thing.
"But now they get to see films like 'Kahaani', 'Paan Singh Tomar' and they appreciate them. Everyone wants a change and there is nothing bad in that. 'Parivartan prakriti ka niyam hai'," he said. After getting appreciation for his role in "Kahaani" and "Paan...", the actor is getting good work.
He has nine films lined up for release including Aamir Khan starrer "Talaash". Other films are "Lunch Box" with Irrfan Khan, "Dekh Indian Circus", "Patang", "Miss Lovely","Gangs of Wasseypur", "Liar Dice", "Chittagong" and "Moonsoon Shootout".
A National School Drama alumni, Nawazuddin says theatre background has been a boon for him, but he has no recent plans to go back to stage.
"Since every character is explored step by step, theatre has really helped me in films. But rght now I am busy with films. Maybe years later I would like to go back to theatre," he said.
