Neel Kamal (1947)
Neel Kamal is a 1947 black and white Bollywood film directed by Kidar Sharma. Although a commercial failure, this romantic melodrama is significant because it features the debuts of two of Bollywood's most important figures, Raj Kapoor and Madhubala. Set in the royal court of Janakgarh, the film opens with the palace coup led by the villainous Mangal Singh, resulting in the deaths of the king and queen. Princess Kamala (Madhubala) and her sister are spirited out the court and given over to a family of untouchables. Later, she and her sister fall in love with a rakish artist (Kapoor), resulting in Kamala having to commit suicide.
