Mahesh Babu's Dookudu unit has completed the family wedding song in Hyderabad. And now the focus shifts onto the final item song, which the unit will start filming from September 6. Director Seenu Vytla's wife Roopa Vaitla is busy working on the casting's costumes and things would be concrete within couple of days. Coming to the movie hype, there's been a huge buzz about Dookudu and the music but Prince Mahesh Babu doesn't want to talk more about the movie and instead await the release.  Wonder Mahesh is playing an underdog and don't want to repeat the mistake of 'Kaleja'.
