Well, I must admit that I haven't watched the old movie.
However, 20 000 leagues... was my first serious book ever. I still remember... I received the book as birthday gift when I was only 7 years old. In first, I was confused with a fat small book without any picture in it, but the front cover illustration was looking so magical to me. So, I began to read, and... I couldn't stop.In a way, this book was an entrance to the fantasy/sci-fi world for me... and what an entrance.
The death of Nemo? Well, he was undying hero to me (besides, Jules Verne brought him back in The Mysterious Island).
I've red recently that remake of classic movie is in plans and it supposed to be filmed in Australia. I have no further info about it.
I salute You.
