The makers of Abhinay Deo's directorial 'Blackmail' have opted for an unusual method to reveal the character posters of the star cast. While the teaser and earlier posters featured Irrfan with a bra and panty paper bag covering his face, now the entire star cast is seen with the same paper bag covering their faces. Continuing the mystery of the paper bag, the character posters too showcase the star cast using paper bags to cover their faces. While Irrfan's identity was hidden in the teaser, the posters intend to hide the identities of the star cast too.
