Malayalam crime thriller 'Oppam', thanks to its content and the scale of BO collections, has been one of the most popular Mollywood movies outside Kerala in a long time.  Pipping the records set by 'Drishyam' and 'Premam', this Mohan Lal-starrer has grossed in a resounding way.  In 3 weeks, the Priyadarshan-directed movie has raked in more than Rs. 27 cr. gross.
