Taking to Instagram, he shared a picture of Ranbir from the sets of the film and wrote: “Director & Actor. Ranbir – The absolute first person to have heard about Brahmastra and the first to have jumped on for the ride! On a writing trip for Yeh Jawaani in May 2011, is where the idea was born… and Ranbir was my very first phone call. There is so much to share about B.astra, but it is fitting that the first team member this Insta journey touches upon is… Ranbir aka Shiva aka Rumi aka Artist aka Soldier! More over the next few… #brahmastra #shivadiaries.
