This is the only film that Madhubala starred in that is completely shot in color. Her most famous film Mughal-e-Azam (1961) has some color sequences, but that film was mostly shot in black-and-white.
Leading lady Madhubala fell ill during filming. The film was shelved for a decade. After her death in 1969, filming resumed with various actresses doubling for Madhubala. The film was finally released in 1971 and wasn't a hit.
Before she became a star, Asha Parekh played a supporting role sharing scenes with heroine Madhubala. A decade later, when Madhubala died, Asha attended her funeral and paid her last respects.
