Thanks for the link. Apparently they are remaking it a third time.

The first one was by far the best. And the closest to the flavor of book - which involved the two kids escaping and their adventures and people that helped them along the way, the girl had these dreams and ESP, while the boy had telekinisis. This version looks like a Rock action film that happens to feature two alien kids with powers. I may rent the original someday, assuming of course I can find it. The problem with remaking these things, is it becomes harder to find the original versions.
