Karan Johar was quick to bag the rights of Hindi remake of Marathi blockbuster film ‘Sairat’. Industry buzz suggests that the filmmaker has now decided to cast Shahid Kapoor’s younger brother Ishaan Khattar in this romantic flick, which will be produced under Dharma Productions. Rumors are rife that ‘Humpty Sharma Ki Dulhania’ director Shashank Khaitan will direct this film, whose script is being worked upon. Shashank is currently calling the shots on ‘Badrinath Ki Dulhania’, starring Alia Bhatt and Varun Dhawan. Ishaan is Shahid Kapoor’s half-brother from maternal side as his mother Neelima Azeem married into the Khattar family.
