Maybe I Dreamed This?

Hi. I’m not sure if I vastly overestimated this, but I remember reading somewhere that Shashi Kapoor was pitching a story to Aamir Khan? This would’ve been around the time Lagaan was being made. (To back this up, I looked in my copy of the book “The Prithviwallahs” by Deepa Gahlot, and it does say that Lagaan has bits from one Prithviraj Kapoor’s plays called Kisan) I swore I read somewhere of this. Does anyone know/remember hearing anything similar to this?
