After weeks of speculation about Alia Bhatt’s next role, the confirmation: she will play an undercover agent in Meghna Gulzar’s Raazi.

Produced by Junglee Pictures and Dharma Productions, the film is an adapation of Harinder Sikka’s 2008 novel Calling Sehmat. Set against the backdrop of the 1971 Indo-Pak war, the movie will see Bhatt as Kashmiri undercover agent Sehmat Khan, who is married to a Pakistani army officer (Vicky Kaushal). Sikka’s novel is based on a real-life story.

Raazi follows Gulzar’s critical and commercial hit Talvar (2015), based on the Aarushi-Hemraj double murder in 2008. “I am trying to do something in a new space, recreating India and Pakistan of the ’70s on sets and real locations,” Gulzar told the Mumbai Mirror in an interview. “A lot of research has gone into getting the period and dialect right. There are some action pieces too.”

Dharma Productions’ Karan Johar made the announcement on Twitter.
