I clicked on all kinds of arrows, and nothing happened!
We will see. I think there is potential there, of course I doubt very much that a movie like Alien will fly again, since its been ripped off in dozens of movies, and even its own sequels, but with the advent of 3-d projection, and its suppossed inclusion in the majority of theaters by 2010, I think there is always a shot.
Some fox executive is going to be sitting around thinking about the next alien sequel in 3-d after Avatar's inevitable success.
The evolution of film itself will keep the series fresh, even though they absolutely will have to present the movie in a different way.
