On the day of her marriage Hema Malini refused to shoot for Kranti. Hema shot for Razia Sultan in the morning and then sent the message to Manoj Kumar's unit that she was ill and did not want to shoot. The real reason Hema did this was because she was required to wear a white saree for a scene. The saree represented her being a widow. She did not want to do that scene on her wedding day . When Manoj Kumar later found out the real reason for her not reporting to the sets , he had a good laugh and call to wish Dharmendra on his wedding .

Prakash Mehra was ready to start his film Zameen with boxing legend Mohammed Ali and Amitabh Bachchan. But he got the scare of his life when he saw the climax of Kranti.

Salim Javed had also seen ROOTS and lifted several ideas from there and put them in Kranti. This ups3t Prakash Mehra because now he would have to rewrite major portion of his film.
