Abburi Ravi, who penned beautiful one liners for 'Bommarillu' and who gave dialogues for 'Annavaram' of Pavan Kalyan was roped in to write dialogues for Nagarjuna starrer 'Don'. It may be recalled that his dialogues in 'Bommarillu' like 'BP Ante Ilaage Vuntundaa Siddhu, Nenu First Time Choostunnanu' evoked tremendous laughter in the theatre. Besides, the dialogues between Prakash Raj and Siddhartha in the climax scene in 'Bommarillu' were also spell bounding. As he had the spark in evoking good laughter with his dialogues and has the capacity to mesmerize the audiences with beautiful conversations, Raghava Lawrence, who gave big hits like 'Mass' and 'Style' as a director, sought his services for his latest flick 'Don' with Nagarjuna being produced by ML Kumar Choudary. The film is most likely to go to sets and launch production formally on December 23.
