Just Watched It
Once more and it was a fair movie. The main disappointment was that it deviated from the book in ways that I didn't think were necessary or desirable. An example of this would be that there was one Ark built in the film and in the book, there were two. The outcome of Tony and Dave's rivalry over Joyce (Eve in the book) was different as well. The two men got along well, and there was no almost-fistfight between them. Tony was a stockbroker in the book and not a doctor.
There was no lottery in the book, and the ship of escape was atomic-powered.
I don't think that these changes, most of them admittedly fairly minor, were necessary or helpful.
This is one of the few films that need a re-make. There should be an adaptation of the sequel, 'After Worlds Collide'.
