I LOVED the movie Final Countdown! What an excellent, thought-provoking example of a time travel fic. There are so many fantastic ways to continue this particular story. Especially the Time Storm!
Hey, if you do continue it, try to fit Charlie the dog into the story, he was so neat in the movie. Hmmm the Tideman Foundation, that makes sense, what a cool way to start Utopia.
H.G. Wells couldn't save them? That is seriously odd.
