"I am hunting for Madhubala but it is too early to talk about it. Casting happens two to three months before we start shooting. The film is in its initial stage and would probably release next year," Anurag said.
While Ranbir has been roped in to play Kishore Kumar's role, there were reports that Kangna Ranaut or Katrina Kaif might step into the role of Madhubala. However, no official confirmation has been made.
The biopic will go on floors soon.
