I have been trying to internalize the character and looking forward to translating my effort onto the celluloid. The film is based on a book written by Manmohan Singh's former media advisor Sanjay Baru and is helmed by debutant director Vijay Ratnakar Gutte, alongside Hansal Mehta as the creative producer. Akshaye Khanna will be seen in the role of Baru whereas German actor Suzanne Bernert will be donning the role of Sonia Gandhi. The film is set to release on December 21 alongside Shahrukh Khan's Zero.
