Quit trying to kill me, makers of "Day the Earth Stood Still"

Let's say you believe in intelligent alien life forms. You believe these life forms have the power of sight, language, and an appreciation for Christmas blockbusters. As it so happens, you live in America, so you quickly find someone willing to beam transmissions into space at your aliens for the low low price of $300/5 minutes. What kind of message would you send them? Maybe a simple greeting; maybe a beautiful piece of music, or a mathematical equation. Or how about a movie about ALIENS COMING TO EARTH AND THREATENING TO KILL US ALL UNLESS WE CHANGE OUR WAYS. Smart, makers of The Day the Earth Stood Still. I'd save you a seat on the Emergency Humanity Evac Rocketship, but I'll need a place to put my stockpile of every Independence Day DVD in the world.
