Don

The producer Nariman Irani was a cameraman who was in deep debt of around Rs 12 lakhs ( a lot of money for that time) after his first film Zindagi Zindagi with Sunil Dutt that flopped miserably. So to get out of this financial mess he was advised by Amitabh Bachchan, Zeenat Aman, Chandra Barot and Manoj Kumar to make another film which subsequently turned out to be Don. Writers Salim-Javed were not able to sell the script for a long time until director Chandra Barot and producer Nariman Irani bought it. It was rejected by Dev Anand, Prakash Mehra and Jeetendra. The script did not even have a name. It was a script pertaining to a character called Don. When Nariman Irani approached Salim, he said, 'Humare paas ek breakfast script padi hai jo koi nahi le raha hai.' And Nariman said 'chalega'. So that is how Don was made.
