Veteran journalist and editor Prabhu Chawla will be seen playing the role of a journalist where he grills Ajay Devgan in the film Halla Bol. The film features a scene where Devgan who plays actor ‘Sameer Khan’ is made to face the firing squad on Seedi Baat, a popular program on Aaj Tak. While the interview will be 'staged' for the purpose of the film,   Prabhu Chawla is looking forward to having Ajay   Devgan on his show for an encore, where the otherwise incisive journo won't have to  necessarily 'please' director Rajkumar Santoshi.
