Maverick filmmaker Ram Gopal Varma has already authored a book that was recently launched at Hyderabad. Now the filmmaker is all set to write his next book, this time on a different subject. It's not about his autobiography, but a book on the latest achievement he has made by making a film within a short span of just 4 days. The film titled 'Dongalamutaa' is a Zero-budget movie starring Ravi Teja, Charmi, Prakash Raj, Ajay, Brahmanandam and others in lead roles. The film has been made a cheaper cost and all that Ram Gopal Varma wants to write is that a film can be made with ideas and 'budget' isn't always a factor. The filmmaker's recent release 'Katha Screenplay Darsakatvam Appalraju' starring comedy actor Sunil and actress Swathi is doing good rounds in box office now.
