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 .
Manoj Kumar sold his property and for 180 days made the film with his own money.
Parveen Babi fainted on the sets of Kranti due to her strict diet regime. She was on keto diet as she wanted to get a heavily toned body with no extra weight for the song "Maara Thumka."
Manoj kumar has went on to say that his matinee idol is Dilip Kumar and his all time career high was to direct him in the movie
Manoj Kumar said as he always took Mukesh as plaback singer of his films, in Kranti, he took his son Nitin Mukesh as Mukesh was no more
