Director Ketan Mehta has chosen Nawazuddin Siddiqui to act in his upcoming film Mountain Man, a biopic on a Bihar-based labourer who did the herculean task of cutting a road through a mountain. Here's both sharing there views about the film. He is a great actor and I feel that he suits the role really well. This is why I went for Nawazuddin, Ketan Mehta told to reporters. Mountain Man is a biopic, based on the life of Dashrath Manjhi from Nagar, Gehlaur, Gaya. In 22 years, he cut a 300-metre-long and 25-ft-wide road through a mountain to link Ghivra mauja of Dashrath Nagar, in Gehlaur Ghati to Atara Prakhand, Wajirganj thereby reducing the distance from 75 kilometres to just one kilometre. Manjhi, fondly called Mountain Man, died in 2007. He was 70.
