No, I actually did not. Did not even know there was a book, or maybe I had just forgotten it. How is it written lol, I can't imagine?
The book series is great, one of my favorites. Arthur C Clarke is a great writer.
There is a good section on the difference between the movie and the book. There's nothing about the end sequence, but it's easy to understand that works a lot better in book form where you read the thought process of Bowman.
Was released as a movie too in 1984
His Rama series is great too and I hope that that will get a movie adaptation some day.
Morgan Freeman is still rooting for one http://www.imdb.com/title/tt0134933/
It dit have a video game in 1984 but it wasn't all that fun. It felt more like an eleborate IQ test. Gameplay was basically collecting puzzle pieces for mostly 'what's missing or next in this logical sequence of symbols' puzzles.
