The "Alien Anthology" may have taken some time to come to Blu-ray Disc, but it has been worth the wait. We received the set directly from Fox so are able to give readers an early sneak peek. The films themselves are presented in both their theatrical versions and extended "special edition" versions, Even Alien3 comes in a half-hour longer version here, and they've gone to the trouble of re-recording bits of dialog and sound effects to clean up the audio from the restored portion to match the rest of the film. It is nice to have the choice to watch either cut of all four movies, and the SE version of the second film really adds depth to the story and the characters making a great film even better. Each film gets the DTS-HD Master Audio 5.1 treatment (the first two films' theatrical cuts are also available in Dolby Digital 2.0 and 4.1 channel mixes). Sound is excellent overall, though perhaps not quite as bombastic as one might expect from such action-heavy titles. It seems like more should be coming from behind us at times, and the low bass rumble of the weapon fire and explosions is lacking ever so slightly in deep extended bass. But these are fairly minor criticisms as the sound is clean, imaging is precise, and dialog is clear and articulate throughout. The video transfers are clearly superior to the DVDs that came before them with rich detail, nicely saturated colors and deep blacks. H.R. Geiger's creepy organic art on the derelict alien ship in the first film has never looked so detailed and powerful and you can practically count the pores on young Sigourney Weaver's face. There are still minor instances of murky blacks, some ringing and softness here and there due to mild use of noise reduction, but overall, the transfers are pristine, considering the age of the films. The first two films, though the earliest, look the most improved here - no surprise considering they have been painstakingly remastered at 4K resolution for this release. Only "Aliens" is presented in its original theatrical aspect ratio of 1.85:1 - nearly filling a standard 16:9 screen with thin black lines at the top and bottom. The rest of the films are presented in a CinemaScope 2.35:1 aspect. The extras are extensive, to say the least (be prepared to spend some time here), with special features available on each disc, plus two entire Blu-ray Discs packed full of additional extras: one with "Making Of" documentaries, interview segments and behind-the-scenes footage, and one disc featuring the "Archives," chock full of seemingly every last piece of material -- text, still photos and video -- supporting the films and their back story. A helpful "MU-TH-UR" mode (with its own tutorial) is included to help you navigate through the massive amount of supplements - even allowing us to go directly to specific chapters on other discs: just eject one and insert the other, and it will take you directly to the requested material. Pop the original disc back in and the player will remember where you left off, asking if you'd like to resume. A nice feature made possible via BD-Java. At least one commentary track is available for each film ("Alien" has two), with every director but David Fincher (Alien3) participating in the commentary fun. All four films also have isolated score tracks (in Dolby Digital 5.1), so you can appreciate the nuances of the film's scores without any distracting dialog or sound effects. Although much of the supplementary materials used here are re-purposed from earlier home video releases (DVD and laserdisc), we found many new and extended interview segments and snippets we'd never seen before. I'm sure die-hard fans will find hours of enjoyment in the set, and the audio and video quality alone is worth the upgrade. I know I can never go back to the DVDs. Highly recommended! UPDATE (10/24): Some early purchasers and reviewers have noted some compatibility issues with the set and certain hardware. We've tested the disc with twelve players so far (OPPO, Panasonic, Samsung, LG, Philips, Toshiba and Sony), with mostly minor compatibility issues noted. On the OPPO BDP-83, the "Director's Cut" of "Alien" begins playing zoomed in with only the top left corner of the image visible. Hitting "Menu" then "Play" restores the image to its proper size. Also a Samsung BC-C6900 plays Ridley Scott's intro video to the Director's Cut of "Alien" squished to 4:3 (should be 16:9). Similarly a Philips BD-P7200 played the Ridley intro in a tiny window at the top of the screen, but the film itself played fine in both versions. But otherwise every player we've tested seems to play the set without issues. Some players are extremely slow to load the disc (particularly older players), but this is to be expected from such a BD-Java-heavy title. BD-Java can use quite a bit of on-board memory and processing power once you get fancy (and boy are these discs fancy!). We've tested the set on the following players: Panasonic DMP-BDT350, DMP-BD85, DMP-BD60, DMP-BD70V and DMP-BD35, Samsung BD-C6900, LG BD390, OPPO BDP-83, Sony PS3, Sony BDP-S350, Philips BD-P7200 and Toshiba BDX3000.
