Helium-3 is a byproduct of the sun's nuclear fusion. Our atmosphere keeps a lot of it off of Earth, but the moon has no such atmosphere.
As for movies, I tried watching "The Last Airbender" tonight (I liked the show, but never saw the movie in theaters). I heard it was bad, but damn, I expected "Alan Smithee" to be credited for it. I don't see how anyone could release this with anything but shame. The waterbending effects sometimes look ok, and the soundtrack is passable, but other than that there's nothing salvageable. The entire movie felt like Shyamalan just took the script from the first season of the show and edited it down until it was an hour and 40 minutes, rather than actually writing a screenplay. The pacing is awful, the acting is awful, the camerawork is awful, the dialogue is inexcusably bad... Wow. I don't think I've ever seen a movie fail on so many levels. "The Sixth Sense" was a great movie, Shyamalan! What the hell happened?!
On a more positive note, check out Fritz Lang's "M". It's in German, and really old (1931), but it's been remastered, and it's on Netflix instant watch. And it's a great movie. So watch it nao.
