Interesting movie with nice twist and turns, nice plot, direction and cinematography as well. Technically very sound movie. I found one flaw through. In the last scene of the movie Se. Bachchan discloses that he called from his cell phone and played the recording of Wazir (Neil Nitin Mukesh) however Farhan looked at the phone and received it saying that ha bol Sartaz. Why would he address Sartaz when the ring came from Dr. Bachchan's phone no? Any thought
