This anthology contains 4 discs, 1 for each film and each film has two viewing modes: The first is the theatrical release, the second is the directors cut with little introductions from the directors. Ridley Scott obviously for the first and so on..
Each movie has had the bluray picture and sound improvements and its definetly been worthwhile. Most noticably with the first film which was released in 1979. Grain still exists but skin tones, close facial shots and the Alien itself all very clear. Also the background clear-up picture where before it was very dark now you can really see pieces of the set, hidden things you would'nt have noticed on the DVD. I never realised the similarities 'Prometheus' had with the first Alien film untill now with the clearer bluray picture.
The same can be said for the next three movies where picture quality improves more and more as you would expect the recent releases to have had less picture grain if any at all.
In the first chapter of the terrifying Alien saga, the crew of the spaceship Nostromo answers a distress signal from a desolate planet, only to discover a deadly life form that breeds within human hosts. Now the crew members must fight not only for their own survival, but for the survival of all mankind.
The terror continues as Ripley (Sigourney Weaver) returns to Earth after drifting through space in hypersleep for 57 years. Although her story about the alien encounter is met with skepticism, she agrees to accompany a team of high-tech marines back to LV-246... and this time it's war.
In the third chapter of the terrifying sci-fi saga, Ripley's crippled spaceship crash-lands on Fiorina 161, a bleak wasteland inhabited by former inmates of the planet's maximum security prison. But an alien was aboard her craft... and soon the body count begins to mount.
Terror is reborn in the stunning conclusion to the Alien sci-fi saga. Two hundred years have passed since Ripley made the ultimate sacrifice on Fiorina 161, but now a group of scientists has cloned her--along with the Alien queen inside her--hoping to breed the ultimate weapon.
Overall a very good set to add to any collection and one of the best looking steelbooks yet.
