In the late 1960's , producer, assistant director Raaj Grover took Amitabh to meet Tarachand Barjatya for a screen test. Amitabh arrived in a taxi cab wearing a white churidar pyjama. This angered Raaj Grovel as he felt the tight fitting pants emphasized on Amitabh long and skinny legs . He told Amitabh what he felt. The appointment was for 11:05. Amitabh and Raj Grover arrived and knocked on the door at 11 pm. This angered Barjatya and he told them that he said the appointment was for 11:05 am not 11:00. The minute Tarachand Barjatya saw Amitabh he said "No heroine will ever want to work with you. You are too tall. Why don't you go and become a poet like your father." After that there was a 10 minute silence in the room. A dejected Amitabh thanked Barjatya for his time and left. Two years lated Tarachand Barjatya changed his mind about Amitabh after seeing the movie Anand. That is when Amitabh signed Saudagar.
Amitabh starred with some of the top heroines of the 1960's in his earlier movies before he became a big star. Nutan in Saudagar. Mala Sinha in Sanjog. Tanuja in Pyar ki Kahani. Nanda and Asha Parekh - both of whom made a hit pair with Rajesh Khanna, never got to play the romantic lead opposite Bachchan though.
In 1994 released Insaniyat Nutan played Amitabh Bachchan"s mother.
This movie was the first ever time that Amitabh Bachchan worked with a member of the Kapoor family, Trilok Kapoor (brother of Prithviraj Kapoor). They would also work with each other in Dostana and he would feature as Amitabh's father (but not appear together) in Ganga Jamuna Saraswati.
