I have been looking at the HMV website and there is 2 Alien Boxsets
Alien Legacy This one is £70.99 and has 4 discs with all for films on.
Alien Quadrilogy This one is £44.99 and has 9 DVD's becuase it has all speical features stuff added and had 9 DVD's 4 of them are the Director Cuts of the films and the 4 are Thectrical Cuts of the Films. And the 9th DVD is a Speical Edition one.
I don't understand why the price difference which one should i buy.
