The theories are bolstered by the fact that his personal physician, who said that Shastri had so sign of a heart trouble before, was killed in a road accident shortly after Shastri's death. Agnihotri had announced in January that he would make a film on the "truth of the biggest cover-up of free India" on Twitter.The Tashkent Files features a stellar cast that includes the names of Mithun Chakraborty, Naseeruddin Shah, Shweta Basu, Pankaj Tripathi, Vinay Pathak, Mandira Bedi, Pallavi Joshi, Ankur Rathee and Prakash Belawadi.
