Irrfan Khan 's quirky comedy, Blackmail revolves around a Blackmail spree that the protagonist Dev aka Irrfan gets embroiled in, upon seeing his wife in bed with her lover. Interestingly, a track in the film is identical to the ongoing CDR row where a detective is involved in the exchange of call data records. The similarity comes as a surprise to the makers who were stunned upon reading reports about the under investigation CDR row in Bollywood.

Says a source, "Irrfan's character comes in contact with a detective to procure call data records, in one part of the film. The striking similarity the film has to a real-life scenario is baffling." The CDR case has become sensationalized as the case is still under investigation. But the makers of Irrfan Khan starrer Blackmail were left astounded when they came to know about the case, as it bears a strong resemblance to an integral part of their film.

The interesting twist in Irrfan Khan's Blackmail has also has happened in reality, which has further piqued the curiosity around the film.
