"Bapsi Sidhwa's novel is written in English, and although she wrote the screenplay in English as well, Mehta decided to make the film in Hindi titled Earth. 'Most of the characters in Earth are working class people and the thought of them speaking English in 1947 felt ludicrous, though some relevant scenes remain in English.'"
