Ghajini (2005) is a Tamil action thriller movie. This is later remade into Hindi with the same name. It is based on Christopher Nolan's Memento. The protagonist in Ghajini suffers from Anterograde amnesia. But the disease is inaccurately depicted in the movie. Sanjay Ramaswamy (Suriya) forgets his memory every 15 minutes.
My question is about Tamil movie Ghajini. Why is the movie titled Ghajini? What is relation between Ghajini and the movie?
