I just saw the movie last night, and none of these videos give the movie away. Your expectations will be exceeded. It is a fantastic movie, both for people who know nothing about science, and people who know a lot about science. (I am a science major, my friend is a music major; we saw it together and were both equally amazed.) For those of you who are upset that the movie isn't scientifically accurate, I highly recommend seeing it so that you can be just as surprised as I was with how realistic it really is.

And keep in mind: there are a lot of things that we as humans (and scientists) still do not know - ESPECIALLY about the sun and outer space. Our idea on how the sun creates its vast amounts of energy is an educated guess-a very good educated guess, but a guess none the less. The great thing about science fiction is that a writer can make guesses about the future, and from these guesses create a story that is imaginative and entertaining for us. This movie has done that: so unless you have a time machine and can travel forward to see just how 50 years in the future will look, you should really keep your mouth shut and enjoy the movie.
