Athiran will be the next from fiery on-screen performers Fahadh Faasil and SaiPallavi. The teaser was released yesterday and has become an instant hit with viewers and critics. The teaser has left many puzzled at the kind of genre it will fit into. The teaser had Sai Pallavi being chained in a dark room and Fahadh tries to start a conversation when he gets hit by her. She is said to be suffering from Autism Disorder. The visual looked eerie and had kept us wondering if it is going to be a horror- thriller or a psycho- thriller. Directed by newcomer Vivek, it is scripted by award winning writer PF Mathews whose last work was Ee MaaYau. Slated for Vishu, the film will release in Malayalam, Tamil and Telugu on April12.
