Bollywood actors Ranbir Kapoor and Alia Bhatt returned from Varanasi after wrapping up their shoot of ‘Brahmastra’.  Ranbir looked hot as ever in casuals and was all smiles for the cameras. Alia was seen in green pant-suit and looked airport ready. Helmed by Ayan Mukerji, ‘Brahmastra’ will hit theatres next year.
