Recently while promoting his new film ‘Robin Hood’, Ridley Scott spoke to collider.com about the alien prequel. It seems Ridley now plans on making two alien prequel films as a lead up to the original classic. When asked if he was developing the new movie as a larger story Scott stated “It’ll be two. It’ll be prequel one and prequel two. Then Alien 1.”
There seems to be no word yet as to whether the two films will be shot back to back or separately however Scott did discuss briefly the challenges filming an Alien movie in 3D would present, primarily in regards to the lighting.
