Born in Indore on November 24, Salim Khan belongs to an affluent family. Salim Khan's grandfather, Anwar Khan, was an Alakozai Pashtun who migrated from British Madras to India in the mid-1800s and served in the cavalry of the British Indian Army. While looking out for employment in government service, Salim Khan's family later settled in Indore.

The veteran screenwriter is best known for being one half of the prolific screenwriting duo of Salim-Javed, along with Javed Akhtar. The duo Salim-Javed were the first Indian screenwriters to achieve star status, and later on became two of the most successful Indian screenwriters of all time.

Salim Khan and Javed Akhtar have spent most of their career working together for Bollywood, where Salim Khan was largely responsible for developing the stories and characters around the movie, Javed Akhtar developed hard-hitting dialogues for the script. The Salim-Javed duo revolutionised Indian cinema in the 1970s.

Salim Khan and Javed Akhtar were not only truly responsible for transforming and reinventing the Bollywood formula, but also pioneering the Bollywood blockbuster format. The duo collectively has given their career to masala films.

Salim Khan was mainly responsible for creating the 'angry young man' archetype character for Amitabh Bachchan, which gave him a different persona altogether in Bollywood. Their films are among the highest-grossing Indian films of all time, including Sholay (1975), the highest-grossing Indian film ever at the time, as well as films such as Seeta Aur Geeta (1972), Zanjeer (1973), Deewaar (1975), Kranti (1981), and the Don franchise. Sholay is also considered to be one of the greatest Indian films of all time.

Salim Khan married Sushila Charak, now known as Salma Khan in 1964, and later, he also tied the knot with Helen Richardson Khan in 1981. The father of three Bollywood actors, Salman Khan, Sohail Khan, and Arbaaz Khan, film producer Alvira Khan Agnihotri and Arpita Khan Sharma, has also won six Filmfare Awards as part of Salim-Javed, and he was later awarded the Padma Shri in 2014.

But did you know Salim Khan refused to accept the Padma Shri honour, the fourth highest civilian award in the country? In an old interview with mid-day, the screenwriter said: 'Now they are offering me the award that the others received much earlier. My contribution to cinema has been much more than what is being offered to me (as an acknowledgement). So, I have refused to accept it.'

Despite giving so many hits to the Hindi film industry, Salim Khan said to the hit-list team that he wouldn't like to pen his star son Salman Khan's films. When asked why, the veteran further added that he would be blamed if the movie proved to be a box office dud, but his superstar son would get all the credit if it performed well.

Only a few would know that Salim Khan had written Salman Khan's 1991 film, Patthar Ke Phool, which did fairly well. The veteran feels that time has come for scriptwriters to get their due as stars usually pocket credit when a film does well.
