Mammootty starrer "Pramaani" will hit the screens on March 18th. The movie was supposed to release on a later date but was pre-poned. It will complete the final stages of shooting this week. Sources indicate that Mammootty wanted to have an early release of the movie since his last movie "Drona 2010" flopped. "Pramaani" has been directed by B Unnikrishnan and also stars Sneha, Fahad Fazil, Siddique..
