Karan Johar was quick to bag the official remake rights of the Marathi blockbuster film ‘Sairat’ to make it in Bollywood. Industry buzz suggests that the celebrity Hindi cinema maker has now decided to cast Shahid Kapoor’s younger brother Ishaan Khattar in this romantic flick, which will be produced under Dharma Productions. Rumours are rife that ‘Humpty Sharma Ki Dulhania’ director Shashank Khaitan will direct the Hindi remake of ‘Sairat’, whose script is being worked upon. Shashank is currently calling the shots for ‘Badrinath Ki Dulhania’ starring Alia Bhatt and Varun Dhawan. As Ishaan Khattar finally makes his big Bollywood debut in ‘Sairat’ remake, he may romance Sridevi’s daughter Janhavi Kapoor in the film. Ishaan is the half-brother of Shahid Kapoor from their maternal side, as Neelima Azeem got married in the Khattar family.
