Randhir Kapoor is a Bollywood actor, producer and director. His nickname is Daboo.
Randhir Kapoor made his acting and directorial debut with Kal Aaj Aur Kal (1971) which also starred his wife, father and grandfather. The film was produced under the R.K banner and was an average success.
After his debut, he scored with two successful movies, the first with Jaya Bachchan in the film Jawani Diwani (1972) which also included the hit song "Jaane Jaan." This movie was one of the biggest hits of that year and was applauded because of the music and performances. The other success, released the same year, was Raampur Ka Lakshman, with Shatrughan Sinha and Rekha, and directed by Manmohan Desai, with music by the legendary R.D. Burman.
In 1975 he directed and starred alongside his father once again in Dharam Karam which was a failure at the box office.
