Fox have commissioned six short (10-15 minute) films to be made to celebrate the 40th anniversary of the ALIENS franchise. The first two are out now.
They're the best ALIEN stories we've seen since possibly ALIEN 3 (if not ALIENS), and it shows the short run format fits the franchise quite well, better than two-hour movies where we can predict half the beats ahead of time. Interesting to see if the quality holds up over the other four.
