'Thanmatra' (2006) turned out to be a wonderfully refreshing experience for film goers, who were once again delighted to experience the brilliance of Mohanlal. He paid tribute to his own inimitable talent through his heartrending portrayal of Rameshan, a Govt employee, who falls prey to Alzheimer's disease. Mohanlal enacted the role with panache, and received the State Award for the best actor.
