The actress is working with John for the first time.

"John is a superstar! Until this film happened, I didn't know him on one to one basis. He is chilled out and humble, a thorough gentleman," Amruta said.

Talking about the film, she said: "I am playing the activist, who is against the special cell, police, government and is protesting against the system. It's a very strong character, who is fighting against the government and the police force, trying to convince people to stand against injustice.

"I am glad I got a chance to work with Nikkhil Advani. He made sure that all his actors were comfortable on the set."
