Mumbai, Jan 31: Salim Khan says one of the reasons why he doesn t want to write for his star son Salman Khan is that if a movie fails, the screenwriter would be blamed for it, but if it works well, people would praise his son for his efforts.During Zee Classic s "My Life My Story", which will begin from February 4, Salim revealed why he doesn t write scripts for the "Bajrangi Bhaijaan" star, read a statement.Talking about Salman, his father said: "It s not that I haven t written films for Salman. I had written a film for him - Patthar Ke Phool which did reasonably well too. "Even today, when I pitch a script, people always have a question that if it is good then why is Salman not acting? But I wanted to get out of that vicious circle."He added: "Another thing is (that) if a movie fails, it is my fault. If it is a hit, it is Salman s efforts!"Salim had teamed up with Javed Akhtar to form the Salim-Javed duo that gave 1970s blockbusters like "Deewaar", "Sholay" and "Don".
