1. Prithviraj Kapoor laid the foundations of Prithvi, a travelling theatre troupe which staged memorable productions across the country. Today, Prithvi is still run by the Kapoors. Prithvi Theatre is more than an institution with a trendy caf, it is a legacy.
2. Prithviraj's son Raj began his Bollywood journey as a clapper-boy. When Kidar Sharma was filming Vishkanya (1943), Raj would always comb his hair and pose in front of the camera before giving the clap. When Kidar Sharma was shooting a close-up as the sun was going down, Raj caught the hero's beard in the clapperboard and it came off. Sharma lost his temper and reportedly slapped young Raj in front of the whole unit.
3. Raj Kapoor first wanted to become a music director. But he turned out to become the youngest film director at 24.
4. Raj's real name was Ranbir, shared by his grandson. Raj was the middle name of all the Kapoor brothers. Shammi's real name was Shamsher Raj and Shashi's was Balbir Raj.
5. The scene where Rishi meets Dimple in her house in Bobby was inspired by the real life meeting between Raj Kapoor and Nargis.
6. Prithviraj's second son, Shammi wanted to be an aeronautical engineer before he joined the theatre and then films. He became a famous actor only after shaving off his moustache.
7. The song "Tum ne mujhe dekha" from Teesri Manzil was shot soon after the death of Shammi Kapooor's wife Geeta Bali. Director Nasir Hussain kept the set ready for three months so that Shammi could shoot whenever he was ready.
8. Shashi Kapoor played Amitabh Bachchan's younger brother in Deewar, Trishul, Shaan and only played his older brother once, in Silsila.
9. Raj Kapoor's second son, Rishi Kapoor, made his debut as a toddler in the hit song "Pyaar hua ikraar hua" from Shree 420. Brother Randhir and sister Ritu also appear in the song. Nargis had to bribe little Rishi with chocolates so he would shoot the sequence.
10. In a goof-up that was never corrected in Amar Akbar Anthony, Rishi Kapoor's character Akbar Illahabadi calls Neetu Singh's character by her real name 'Neetu' instead of her screen name Dr.Salma in their first scene together.
11. Neetu Singh hated Rishi Kapoor because he used to constantly play pranks on her. On the sets of Amar Akbar Anthony, he smeared kajal on her face forcing her to redo her make-up.
12. Randhir and Babita's elder daughter, Karisma, was actually the second Kapoor girl in Bollywood. The first was Shashi's daughter Sanjana who made a debut in Hero Hiralal (1988), opposite Naseeruddin Shah.
13. Karisma was not the first choice for Raja Hindustani. The movie was meant to be Aishwarya Rai's debut, and Karisma got the role after Ash dropped out because of her Miss World commitments. The film became one of the biggest hits of Karisma's career.
14. Kareena Kapoor was named after Leo Tolstoy's book 'Anna Karenina' which her mother Babita was reading when she was pregnant.
15. Ranbir Kapoor is a mama's boy. He has Neetu Kapoor's number on speed dial and she still gives him pocket money of Rs 1500 a week. She calls him 'Raymond' because she thinks he is the perfect man.
