The film was first assigned to composer Roshan who passed away during the making. Later Shankar Jaikishan were signed for the same and Jaikishan also died during the making. The heroine was originally Nutan. She had acted in producer Hari Valia's earlier venture, "Laatsaab" but due to a misunderstanding with Sanjeev Kumar, she stepped out and was replaced by Bindu's sister (and composer Laxmikant's sister-in-law) Reshma.
