nothing is known yet except that ridley scott has agreed to become more than seriuosly involved in making a sequel...or maybe a prequel, to one of the greatest, if not the greatest, sci-fi films of all times.
more news to come, shooting is, if everything goes well, supposed to begin in 2-3 years
he says the one thing he does know is that his recalcitrant star from the classic film will most likely not make an appearance
that, for those unaware, would be harrison ford
