After reading a draft of the script, Karan has apparently asked Ayan Mukerji to make few changes

 Karan Johar launched Ayan Mukerji under production house with Wake Up Sid. Ayan had earlier assisted Karan and received a lot appreciation for his debut film. Ayan considers Karan as his mentor, so he said to have showed the script to Karan first who apparently suggested a few changes. A source says, “Karan is close to Ayan as well as Ranbir Kapoor and Alia Bhatt. So when he saw the script and found some issues in it, he asked Ayan to change it. Ayan has agreed to do incorporate it in his script and then he will start shooting.”

 It is said that Dragon is a superhero film, and it needs a lot of pre-production work to be done. The film may also star Amitabh Bachchan. Ayan has said that his hero Ranbir will not exactly be a typical superhero but will have some special powers. The film is slated to go on floor in October and before that Ranbir and Alia will start prepping for it few weeks in advance.

 Ranbir has just wrapped up shoot of Sanjay Dutt biopic in New York recently, while Alia is currently shooting for Meghna Gulzar’s Raazi with Vicky Kaushal.
