Flying Sikh Milkha Singh took just one rupee from Rakeysh Omprakash Mehra to allow him to make a film on his life. What's special about the currency note is that it was printed in 1958, the year when the athlete won the first gold medal for independent India in the Commonwealth Games. The biopic titled Bhaag Milkha Bhaag features actor Farhan Akhtar in the lead role and is slated for a July release. "We wanted to give a priceless token of appreciation to Milkhaji for letting us tell his story through our film. We looked for that something special for a very long time. Then we finally ended up sourcing a special Rs. 1 currency note that was printed in 1958," Rajiv Tandon, CEO, Rakeysh Omprakash Mehra Pictures Pvt. Ltd, said in a statement.
