I think I'm gonna put a moratorium on all these 3-D announcements, seeing as how we can pretty much expect that every major film for the forseeable future will be shot using the technique. This one is a bit more interesting than the rest, though, as it's been confirmed that Ridley Scott's upcoming prequel to Alien will be shot entirely in 3-D.
Scott, who directed the first Alien film way back in 1979, has long since expressed his desire to go back to the origins of the insect-like creatures. The prequel will be a direct bridge to Alien, showing when the creatures were first discovered and exactly who created them.
