U know raman raghav was a psycho killer who killed so many people at the last of 1960.however there was a meassage where director tell that the movie is NOT about himso strange no? the navazudeen sidhiquii was very awesome so that film becomes quite interesting.when u reach at climax only to jump from your seat is remained.as we know the bollywood have less great kinda story film .I the nawazudin sidiqui is one of the best actors from bollywood industry right now.the best part about him the acting he does look natural
