Brahmastra: Amitabh Bachchan, Ranbir Kapoor and Alia Bhatt prep for Ayan Mukerji's movie

Amitabh Bachchan, Ranbir Kapoor and Alia Bhatt star together for the first time in Brahmastra, which is being helmed by Ayan Mukerji and produced by Karan Johar's Dharma Productions.

While Ranbir Kapoor and Alia Bhatt, along with Mouni Roy shot for the first schedule of the movie in Bulgaria towards the start of 2018, Amitabh Bachchan is yet to commence shooting for the same. Ranbir, Alia and Ayan were spotted outside Big B's office in the city as they began prep with the legendary actor. 

Ranbir looked handsome in a black and white plaid shirt which he paired with a simple white tee, blue jeans, white sneakers and a black snapback. Alia looked cute as a button in a green dialogue sweatshirt which she paired with black tights and her hair was tied in a tight bun. Big B kept it sporty in a velvet marron hoodie and matching trac pants along with a black and maroon beanie.
