The "Parched" star says most of the good actors in the film industry come from a solid training background but also lauds the younger stars like Ranbir Kapoor, Ranveer Singh and Alia Bhatt for bringing realism in their roles.
"What training does is, it makes you aware of what good acting is. I feel there is a difference between trained and untrained actors. It does show on screen. But that distinction is something I think in our country the 'aam junta' doesn't understand," Tannishtha told PTI.
The 36-year-old actress, who has worked in both, international and Hindi cinema, says Bollywood follows a particular template of acting.
"With due respect to all our stars, they have played themselves, whoever or whatever they have done, they are still themselves. That is the style of acting Bollywood has always followed. You see the effort, you don't become the character. That effortlessness needs training."

"It is difficult to break," Tannishta says when asked about stereotypes.
"This whole typecasting thing is very difficult. Some of my friends like Nawazuddin and I always discuss that how do you break that. But some of us, in the art-house zone, have been lucky to get different roles. I have played everything from a physics teacher to a villager and now, this role in 'Lion'."
Based on the non-fiction book "A Long Way Home" by Saroo Brierley, "Lion" has received six Oscar nominations at the 89th Academy Awards.
"This is the only thing which is not there in the book. He said he had created something which we both had never done before and asked us to read the script. When I read it, I felt I could do something interesting with it."
In the film which stars Dev Patel, Priyanka Bose and Deepti Naval, Tannishta plays a grey character, a departure from the roles she is otherwise offered here.
"Lion" will release in India on February 24.
