So this all is known. But what is not known is that Mr Perfectionist had thought of casting Junaid Khan in the film to play the younger Tom Hanks. Yes, you heard it right. Aamir's son Junaid who assisted Rajkumar Hirani on PK was more or less ready to don that role- until there was a change in plan at the last minute. It is not yet clear why they didn't stick to casting Junaid. Instead it was decided that Aamir only should lay the younger Tom Hanks- perhaps due to the fact that Aamir has always pulled off the younger role rather easily.

So, no Junaid in Laal Singh Chaddha, which is the working title of the film in question.
As for how did the adaptation of Forrest Gump happen, Aamir had said, "The writer of this film is (actor) Atul Kulkarni, and it’s a strange story. When we were doing Rang De Basanti (2006) together, he asked me one day what my favourite film was. And I said Forrest Gump. Exactly two weeks later, he told me he had a script for me. He had never written anything before, so I was surprised and asked him what it was about. He didn’t tell me anything but asked me to take out time to listen to it. A month went by and then another, because I was busy. Finally, just to get me to listen to it, he revealed to me that he had adapted Forrest Gump.

Apparently, after I told him Forrest Gump was my favourite film, he came up with a screenplay in the next 10 days. And that made me want to avoid listening to it even more! (Laughs) It’s Forrest Gump, and it was Atul — I was wondering what he must have written... I just couldn’t bring myself to take him seriously! But he would keep reminding me and finally, I heard it two-and-a-half or three years later. He would keep reminding me, so finally I gave in and decided to hear his story. It blew my mind.

After I liked Atul’s adaptation, we started the process of getting the rights of the film. It’s taken us eight years to do this. Obviously we couldn’t make the film without the rights. Advait (Chandan) will be directing it and we’ll be shooting this film across Delhi, Punjab, Himachal (Pradesh) maybe, mostly locations in the north. We’re still doing recce to find locations."
