"When I decided to work on this story, it was not only about an actor... it was a challenge to bring about the seriousness and intensity of the character of a librarian because I wanted to show a span of 20 years in this film without any dialogues and make each frame of the film look magical," Mishra said in a statement.
"I was already working with Tom Alter sir in other projects and I had always seen him carrying a book in his hand. Whenever he used to get free time on set, he used to read books. When I narrated the story of 'Kitaab' to him, I was able to imagine the character of John in him and he himself was so impressed by the role and the story that he said 'This role is made for me'. He also assured to work in the film," he added.
