All the facts from the movie can be verified and that's the great thing about this movie.
There comes a line from the movie which say that a mother is ashamed because her son doesn't know who was Lal Bahadur Shastri who penned down 'Jai Jawan Jai Kisan' white revolution, green revolution was the biggest thing someone had done for the country. How even socialism was added to the constitution and yeah I even didn't know 2nd October is also Shastri jee's birthday.
Well done Vivek Ranjan Agnihotri..
Biggest thing is he hated casteism so much that he pulled down his title for the same yet there's no history about that...The then government didn't bother to conduct post-mortem coz they knew his organs were taken out..Great
