Khan told IANS: "Around 14 years ago, Atul Kulkarni, who is the writer of the adaptation, and I were talking one night. He asked me, 'What is your favourite film?', and I said 'Forrest Gump' is one of them. I named a few more also. But somehow, we got talking about this film and then the night got over. He went home and I forgot about it.
"Two weeks later, he called me and said, 'I have written a screenplay for you.' So, I said, 'But you don't write'. He replied, 'Yeah. But I have tried to write and I have written it.' I asked, 'In two weeks?' And he said, 'Yes'. He said, 'I have written an adaptation of Forrest Gump.
"At first, I started laughing. Forrest Gump is such a classic you don't want even to attempt a remake. Plus he's done it in only two weeks. And this is the first script he has written.
"So, I didn't take it very seriously. It was my folly actually that I didn't take it seriously. I didn't hear it until two years (had passed). The day I heard Atul's narration, I just fell in love with it."
"I found it so beautifully done. How can something like Forrest Gump, which is so deeply rooted in American culture be made in any other culture?, I could not understand. But Atul showed me how. It was Atul's adaptation that made me do it," Khan added.
The film, which features Khan and Kareena Kapoor Khan in the lead roles, releases on August 11.
