^Never saw the movie, but I read the book a couple of years ago. I don't recall if that Krishna story was in the book. I liked some aspects of the book, but overall I was a bit disappointed in it. That's just me, though.
That story is definitely in Life of Pi. It says that Krishna has been wrongly accused by other children of eating dirt. He denies it and his foster mother says "Tut, tut, open your mouth". He does and she sees the whole complete entire timeless Universe. I loved the book and I can't wait to see the movie which opens in Australia on New Year's Day.
I've linked to this New Yorker piece before, but for those who haven't read it, here it is again. The 1970s TV miniseries Moses the Lawgiver, starring Burt Lancaster, was also a fairly intelligent dramatization of the story of Moses and the Exodus, taking a historic and anthropological approach to the material and downplaying the supernatural aspects. (I'm tempted to say it wasn't run of De Mille, but that would be too easy. )
There wasn't anything particularly special about the story itself, but the film was very well done, imho. On the other hand, I liked the element of.faith/religion and a young man's struggle to survive in the middle of the ocean.
^That is why I was disappointed. I was expecting something deep and meaningful, but I got a book about believing in god. I don't believe in god, and I never have. Not that aspects of the book were not meaningful or enjoyable to me, allegorically, and I certainly appreciated the technical aspects and worth as a piece of literature -- but I don't find any worth in faith.
^Oh, I had no problem with it. It is just that it was not the experience I expected -- hence disappointment.
I didn't know much about the book before I read it as I selected it out of 1001 Books You Must Read Before You Die so I didn't know what to expect, in the end I was pleasantly surprise by how much I enjoyed the novel.
The most fascinating interpretation of that is that God never fully understood his own creations until he actually became human and underwent the whole cycle of birth, life and death (and a very painful death at that). Ever since then, he has never bothered us humans again. But the real life answer is that Jesus and his followers simply had a different understanding of their frumpy religion that had always been based on aggression and fear.
