In "The Day the Earth Stood Still," a remake of the 1951 science-fiction classic, an alien named Klaatu (played by Keanu Reeves, right) visits Earth to save us humans from ourselves. The story is a work of science fiction, with the emphasis on fiction, says Seth Shostak, a senior astronomer at the SETI Institute and a technical adviser on the film. For example, to be able to detect a dangerous buildup of carbon dioxide in our atmosphere and come save us from global warming, an alien that could travel at light speed would have to reside no more than about 50 light-years away. "I doubt that there are any aliens that close," Shostak says. And even if there are, "they might not care about our problems."
Scientific accuracy aside, Shostak says the film could hook a new generation on space science, just as the original film helped direct his career, which is dedicated to the search for E.T. As kids stumble out of the theater, they might ask, do aliens exist?

This appears as news, but it is part of the hype for Reeve's new movie. 'The Day the Earth stood Still' a remake of a classic Sci-Fi movie.
The movie is also being hyped by FOX, with their gimmick of beaming the movie into the galaxcy so that E.Ts can watch too.
Never the less, I can't imagine that we are all alone in this universe.. With a trillion stars in our own galaxcy, and billions of other galaxcies out there.
