"Proud of this inspiring story of a son of the soil of Gaya, the great land of my ancestors," Sinha, who hails from Gaya district, said in his tweet message.
"A dynamic, realistic and timely film of Bihari pride and the original, strong DNA of a son of Bihar," Sinha said.
He hailed the decision of state governments including that of Nitish Kumar in his native Bihar, to provide tax rebate to the movie that was released yesterday.
"The earthy "dynamite" Nawazuddin Siddique is the discovery of the century. Radhika Apte is lovely and laudable. Wish roaring success," Sinha, who himself has acted in more than 200 movies in Hindi and other languages, tweeted.
