Alia Bhatt, who is currently riding high on the success of Gangubai Kathiawadi, has bagged the biggest movie of her career so far. The actor is all set to make her international debut with the spy thriller, Heart of Stone. Tom Harper's directorial venture is headlined by Gal Gadot, who is also a producer of this Netflix project. Heart Of Stone is touted to be the beginning of a franchise in a similar space like Mission: Impossible, but with female leads. The film also features Irish actor Jamie Dornan, who has previously earned BAFTA, Golden Globe and Screen Actors Guild Awards nominations for his performances. While Gadot has reportedly begun filming in the UK recently, we hear Bhatt will start filming her portions a little later as she has to wrap up her prior commitments, like Karan Johar's Rocky Aur Rani Ki Prem Kahani.
