Taapsee Pannu is busy promoting her next, ‘Badla’, a thriller. The actress has teamed up with her ‘Pink’ co-star, Amitabh Bachchan, once again for this film. Warning the audience about the film, Taapsee says, “It is after long that a who-done-it kind of murder mystery is coming out. It is not a very common genre. If you take a break for even a minute, you may not understand what has happened. You will have to sit with complete focus.” While Taapsee plays the victim in this Sujoy Ghosh thriller, Amitabh Bachchan portrays the role of a lawyer who attempts to bail her out.
