Karan Johar has reportedly made the stars of his upcoming film ‘Kalank’ sign non-disclosure agreements to keep all the details of the project under wraps.

Johar himself has been very protective of the film, sharing that “We will have a press conference next year because the film releases in April (2019). I have not given any permission to talk about the film to Madhuri (Dixit-Nene) as well. There will be a press conference in April and Madhuri can talk about it only then.”, The Asian Age reported.

While not much is known about the period drama, reports suggest that Dixit-Nene will be playing the role of a dance teacher. The film also stars Sonakshi Sinha, Alia Bhatt, Varun Dhawan, Aditya Roy Kapur, and Sanjay Dutt
