Alia Bhatt hurt her foot on the sets of Kalank as she slipped on the stairs. Her foot had to be bandaged but the actor preferred to continue shooting for the film owing to its tight shoot schedule. Kalank is Karan Johar’s dream project, also starring Varun Dhawan, Aditya Roy Kapoor, Sonakshi Sinha, Sanjay Dutt and Madhuri Dixit.
