"Mohit Suri, you are the only one who can musically explore the depths of this story and touch the world with your cinematic skills,' Bhatt posted on his Twitter page Tuesday.
The movie was recently in the news due to rumours that Shraddha Kapoor was going to replace Vidya Balan as the lead heroine. However, Bhatt clarified it last week by tweeting: ''Humari Adhuri Kahani' Vidya Balan ke saath hi poori hogi (The film will be completed only with Vidya Balan)."
The film will also feature Bhatt's other nephew Emraan Hashmi, as well as acclaimed actor Rajkumar Rao.
Mohit's past directorials include 'Kalyug', 'Raaz - The Mystery Continues', 'Murder 2' and 'Aashiqui 2'.
