This month we took the suggestion of numerous GWCers and skipped the normal voting process, instead selecting 2001: A Space Odyssey as our monthly group read in honor of Arthur C. Clarke's recent passing.
The book and movie were written concurrently, and the story is largely based on various Clarke short stories. Wikipedia has a great rundown on some of the differences between the novel and movie, but the best way to discover them is to snag yourself a copy and read it for yourself -- along with your friends here at GWC!
2001 Group Read Discussion [GWC Forum]
For anyone whose skeptical because the movie ending didn’t seem to make any sense – reading 2001 did for me what reading Godfather did for me for the ending of that movie – it all made sense after I read the book and saw what was going on under the surface. I then went back and watched the movie and I got so much more out of it.
