Filmmaker S.S. Rajamouli, who gave blockbuster films including 'RRR' and 'Baahubali', says that Ranbir Kapoor starrer 'Brahmastra' will take Indian culture to the world. He said on Wednesday that what he liked the most about Ayan Mukerji's upcoming magnum opus is that it is a commercial way of telling the story of 'astras'.
