Amitabh Bachchan is India’s biggest film star. He is the star of more than 150 movies, and he lives in Mumbai with his wife, Jaya Bhaduri, his son, Abhishek, his daughter, Shweta, and his daughter-in-law, Aishwarya Rai. His daughter is a TV presenter but the rest of his family are all actors.
When we met and interviewed Amitabh, he was working on three different films at the same time. India makes the largest number of films per year in the world – a lot more than Hollywood – so actors work very hard. Amitabh starts work at nine o’clock in the morning and finishes quite late in the evening. It’s often seven o’clock before he goes home. And he hardly ever gets a day off.
Amitabh became a film star in the 1960s when he left his home town, Allahabad, and came to Mumbai, the centre of the Indian film industry. In his early films, he was an action hero and a romantic leading man. Indian films are very different from American or European films. In many films, there are action scenes, comedy scenes and dance sequences, and there are often five or six songs.
Family is very important to Amitabh. In India, families usually live together, and that’s why his son, daughter and daughter-in-law all live at home with Amitabh and his wife. Amitabh told us that, after a day in the studio, they don’t often go out like film stars do. They spend their evenings together as a family, talking and watching TV or a film. They hardly ever go out for dinner. AndAmitabh never goes out on the streets in Mumbai. He can’t, because he’s too famous!

a)      What does Amitabh’s daughter-in-law do?
b)      What was Amitabh doing when they interviewed him?
c)      What time does Amitabh finish work?
d)      Which city is Amitabh from?
e)      What do Amitabh and his family usually do in the evening?
