Mehra's upcoming venture, inspired by the love tale of Sahiban and Mirza, is written by noted filmmaker, lyricist and author Gulzar.
"I did not want to take known actors because they come with a certain baggage and the audience is familiar with them. The film is a fresh take on the this legendary love story, so it needed young, fresh faces," Mehra said.
The 51-year-old director, who has so far worked with stars like Amitabh Bachchan, Aamir Khan and Farhan Akhtar, knew he had found his Mirza, when he met actor Anil Kapoor's son, Harshvardhan.
Mehra is entering a new territory with 'Mirziya', as he has never experimented with love stories before but the filmmaker does not consider it a challenge.
"'Mirziya' is not a risk. I don't see my films like that. I tell stories I want to and I believed in the story of 'Mirziya'. There is no pressure on me to make certain type of movies," he said.
