Director Karthik Subbaraj known for his pathbreaking films in recent times is at it again with 'Mercury' starring Prabhu Deva and Remya Nambesan which would be a silent horror thriller film.  Since all the actors had to convey their roles through expressions the direction team held a forty day workshop for all the actors to get acclimatized.

Due to some unforseen circumstances a famous Kannada actress who signed on to play an important role had to walk out and Indhuja of 'Meyaadha Maan' fame replaced her.  The entire 'Mercury' team were amazed by Indhuja's performance for her scenes which she did without the training her costars had.  The film will be the first to release once the Kollywood strike is called off.
