What's Your Favorite Space Movie?

In the old days, you'd hire an artist to sort of paint. Now we have all the data, all the trajectories. We reproduced the collision, the asteroid collision that took out the dinosaurs. By theay, we have scientists as well as scientifically literate artists who can take the data and turn it into the beauty of these journeys that we share with our audiences. What is my favorite space oriented movie? I have two. And then i have my favorite syphy movie, which you didn't ask me about.
