Raj Kapoor
Though Prithviraj went against the wishes of his parents to become a cine star, he wanted his son Raj Kapoor to study and get a steady job.
But Raj was destined to be called the showman of Indian cinema.
He made his first film appearance in Inquilab (1935) as a child artist. He was 8.
At 16, he made his debut as an adult in Hamari Baat, opposite Suraiya, and Jail Yatra, opposite Kamini Kaushal, both in 1943.
He was barely 21 when he directed his first film, Aag (1948). He starred in the film as well, opposite Nargis. The film was a huge hit, and the partnership lasted through 16 more films, including Barsaat (1949), Shree 420 (1951), Awaara (1951) and Aah (1953).
