Aamir Khan has his own 'different' point of view on the subject, as always. The actor does not believe in remakes at all and gives a very valid reason for that; repetition! Aamir does not like to repeat himself or even copy other actors, however great their performance might have been in the original!
However, Aamir does not rule out the possibility of a sequel to one of his own films. He gives sequels a new terminology- Taking the story forward. As per the actor, producer and now director, the story of one of his favourite roles, that of ACP Rathod, in the hard hitting, Sarfarosh (1999), is still incomplete. The story ended at a point where Rathod was still alive and so were the other lead protagonists, and therefore he feels that the story can be developed and taken forward.
Interesting, one must say. Is the director of Sarfarosh, John Matthew Mathan listening?
