1, 2001: A Space Odyssey predicts many amazing things about traveling on the moon. People can take a special airplane to the moon. There are many things you can do when you are in this airplane, such as eating, calling your family, and having a meeting. Thre are also waitress for travelers, professors and astronauts. Most of those predictions are achieved tody.
2,I don't know about CGI so much, I just know it's about computers. The computer technologies in this movie are amazing. Such as a special machine can record people's voice, when people say their names and destinations clearly, the machine will know who you are. Maybe we don't have this computer technology today, I am not sure...
3. About this movie, actually I don't really understand what it say, I like the music though. My favorite sequence is the waitress walks in the airplane, she is very carefully, moreover, she can walk any ways, she doesn't fall. And when the pen flies, she catches it. It shows us there is no gravity on the moon. I am interested in that.
