Megastar Mammootty is all set to put on the police uniform, once again. Though his last outing in Khaki, Kasaba, failed to do wonders, the reports regarding the new movie give a hope. As per the source quoted in the report, this movie will be the directorial debut of cinematographer Shamdat. This film will be a crime thriller with Mammootty as an investigative officer. But the source added that the movie won't have a heroine as such. This yet-to-be-titled flick will have Kattappanayile Rithwik Roshan fame Vishnu Unnikrishnan and Lijomol in important roles. The movie will hit the floors on March 24 in Kochi. The movie will also be shot in Chennai and Pollachi.
