Says a source, "Initially Salman did show interest in the film. But then  when it was time to accompany the rest of the Ready unit, Salman  opted out because of the controversial nature of the subject and also  the fact that he has earned the wrath of the Tamilians by embracing  endorsing and visiting Sri Lanka twice in a month." 
More importantly, Raavan is worshipped by certain sections of the  Sri Lankan people and the film did raise hackles when released in Sri  Lanka. 
Understandably, Salman was advised against accompanying his friends for Raavan.  Mahesh Manjrekar who's shooting with Salman in Sri Lanka confirms the  fact that Salman did not accompany him and the others who saw Raavan  on Saturday. 
"I went with my friends. But it went very peacefully. I had also heard  that the Sri Lankans were offended by the way Raavan was  depicted. But there were 500 people in the theatre and they watched in  rapt attention." 
Since the movie theatres in Sri Lanka do not allow edibles, Manjrekar  and his friends had taken their own snacks. "We had a good time. Wish  Salman accompanied us."
