The truth behinf ghajini's mysterious title..

Aamir Khan's upcoming next, unusually titled, Ghajini has had left everyone wondering. Everyone has been thinking about what the heck is the meaning of it. Yes it was the name of the original Tamil version of the film directed by A.R.Murugadoss who is also directing the Hindi version. But no one understood what it meant. A large section of the media and Aamir's fans alike were also thinking Ghajini is Aamir Khan's character's name in the film. But is it?

According to our unit sources, "Ghajini is not the name of Aamir Khan's character in the mystery thriller. It is actually the name of the villain whom Aamir's character is trying to find throughout the film as he is the one who has murdered his girlfriend (Asin) and left him severely injured leading him to an extremely disturbed state of mind. The character of Ghajini is played in the film by actor Pradeep Singh Rawat who also played the same role in the original. He had earlier acted as the hot blooded Sardar in Aamir Khan Productions' Lagaan (2001). In fact the villain has a double role in the film. So now there is Ghajini 2 also in Ghajini one can say!"

Has someone who has seen the Tamil version confirm this?
