Ridley Scott directed Alien back in 1979, the film was a huge success and made a star of Sigourney Weaver and spawned three direct sequels in Aliens ( James Cameron ) Alien3 ( David Fincher ) and Alien Resurrection ( Jean Pierre Jeunet ) as well as two spinoff's in Alien vs Predator and Alien vs Predator: Requiem.
For many years there have been discussions about taking the film series back to it's roots and making a prequel based around the space jockey seen in the original film and learning more on the origins of the aliens.
In an interview Scott said "It's set in 2085, about 30 years before Sigourney ( Ellen Ripley ) It's fundamentally about going out to find out 'Who the hell was that Space Jockey?' The guy who was sitting in the chair in the alien vehicle – there was a giant fellow sitting in a seat."
When asked if the movie would be shot in 3D Scott replied "Of course, it'll be 3D" he was also asked about the 3D technology that James Cameron used for Avatar, his reply was "No, I think they’ve already moved beyond. Jim said that this technique, which had taken them four years, he’d said that now you could do it in two. Technology’s shifting all the time. I could have converted Robin Hood. They’d said last October, I could have squeezed it under the hammer and got it in as a 3D version of Robin Hood" he went on to say there are issues with shooting 3D in the low light that an Alien movie requires but they could fix this in post using computers.
Although the screenplay has already been written by Jon Spaihts it's currently undergoing the usual fine tuning that happens to all major screenplays, Damon Lindelof ( TV show Lost ) is working on polishing up the Alien prequel script and it should start filming within the next few months.
The Alien prequel is called Prometheus and should be hitting cinemas sometime during 2012 and it will star Noomi Rapace, Charlize Theron, Michael Fassbender, Kate Dickie and Guy Pearce, the trailer is out now and looks great.
