Filmmaker Nitesh Tiwari and producer Namit Malhotra reportedly consulted pandits and researched ancient Vashisht Yoga Shastras for the upcoming film, Ramayana. They worked on pre-production for 10 years to make sure the script, screenplay and dialogues were put in place correctly. Ramayana will star Ranbir Kapoor as Lord Ram, Sai Pallavi as Sita and Yash as Ravana.
